Daniel Salazar d3869b7846 feat(notifications): dismissal across devices, high priority, buttons, schedule updates, docs fixes (#4501)
- Docs: status(), browser limits, events worker fetch/ack, update() across
  pages, stored-notification retries, device removal, push delivery, queue
  coalescing, existing service workers and missing error codes match the code.
- puter.notifications.markShown(uid) / dismiss(uid).
- Dismissals reach the app's live feed (on('dismiss')); pages close the
  notification on screen, and a later page load closes ones already dismissed.
  The desktop closes its own copies on notif.ack.
- Live notification postings are forwarded to sessions in other regions.
- notify({ priority: 'high' }).
- onPush() results accept requireInteraction and actions; clicks carry action.
- replaced reaches service-worker onPush() handlers.
- puter.events.updateSchedule(scheduleId, changes), with the invoker
  re-checking a schedule run's guard right before it is sent.

* docs: refresh KV sharing, Events and Notifications docs and recipes

Bring the KV, Events and Notifications reference pages and the recipes that
use them in line with current behavior, and tighten them.

- KV: share levels, re-share and recipient rules, handle scoping, list
  limits, the 399 KB value limit, and full error tables per method.
- Events: kv:<handle> subjects, what each way of losing access does to a
  subscription, fetch() notification types, handler ownership, and accurate
  anchor-deletion and deleted-app behavior.
- Notifications: where a push goes, desktop and website behavior, sensitive
  taps, share-notify limits, and enable()/status() errors.
- Recipes: fix broken code paths (undefined helpers, single-page share
  listings, read-modify-write races, oversized batch writes, missing value
  fallbacks), use events.update(), onlyIfAbsent and batch share recipients
  where they fit, and cut repetition.
- New recipes: Add a Notification Settings Switch, Clean Up Background Work.
- Rename push-when-closed to reach-a-user-when-your-app-is-closed, drop
  playground examples that need an app the reader owns, and redirect both.

* fix(workers): send CORS on router 404s and readable 500 bodies

Unmatched paths and methods now carry Access-Control-Allow-Origin like
every other router response, so a browser sees the 404 instead of a CORS
failure. A handler response with immutable headers is copied rather than
turned into a 500, and a thrown puter.js error object is sent as JSON.

* fix(kv): one error code for oversized values, and SDK types that match the store

The store now rejects a value over 399 KB with value_too_large, as the
SDK's own check and a growing path write already did. get() declares its
batch form, and the JSDoc gives the 399 KB limit and says watch shares
can list keys.

* docs(notifications): notifications sent within 250 ms reach live listeners as one

* test(events): give the per-handle subscription cap test room on a loaded runner

It fills the whole cap of 1,000 session subscriptions one add at a time,
which went past vitest's 5 s default on a busy CI shard.

Daniel Salazar dd144b6b64 feat(notifications): notify through KV shares, group replacement, fewer push prompts, and events/worker fixes (#4432)
* feat(perms): add a pushNotifications resource to puter.perms.request

notifications:push gets a resource like backgroundEvents, so it can be
batched with other access behind one prompt. requestPermission() and
hasPermission() ask through it.

* fix(puter-js): read puter.gui_features once at load

The desktop's feature list was read from location.search on each call, so
an app whose router rewrote the URL lost it and enablePush() and the other
desktop dialogs answered as if the desktop lacked them.

* feat(gui): ask for notifications:push when an app calls enablePush without it

enable() and enablePush() inside the desktop answered unavailable for an
app without the push permission. They now show the permission dialog,
whose Allow also starts the browser registration, and answer with the
browser's push state once it settles, or off when denied. A browser that
blocks notifications or has no push service still answers without a
dialog.

* fix(kv-share): charge mint and grant budgets only for share calls that change something

A share call now spends the per-call mint budget and the per-recipient grant
windows after it has looked up which recipients already hold the share. A call
whose recipients all hold the share at the requested level and label spends
neither. Recipients without the share, including unknown usernames and refused
recipients, still spend a grant unit each. Every named recipient spends from a
new 1,200/min lookup window before any lookup runs.

* perf(events): skip the subject split for rows not made through a share handle

kvHandleFromSubject checks the stored subject's kv:kvh- prefix before
splitting it, so own-namespace and fs rows return null without parsing.

* feat(notifications): resolve enable() on a website before the confirmation push

enable() waited up to 30 seconds for the confirmation push, so a prompt
the same click started next had lost its activation. On a website it now
resolves once the browser answered and the server has the subscription,
records the opt-in, and finishes the confirmation in the background. A
failed confirmation goes to onPush's onError and the next load's resync
tries again. disable() and sign-out stop a confirmation still waiting.
The GUI keeps waiting, since it reads the registered device right after.

* fix(notifications): show a page's own notifications only while push is on

A hidden page with an onPush handler kept showing notifications after
disable(), and its receipts kept claiming showsOwn, which held pushes back
from the user's other devices. Both now need the user's opt-in, cached in
the page, refreshed on enable, disable, sign-out and each sync, and re-read
when another tab of the site changes it.

* fix(events): leave subscriptions suspended for good out of the durable quota

countForHolder no longer counts rows suspended with a reason that never
resumes (permission_revoked), in both the pre-insert check and the recount
after insert. Rows suspended for a resumable reason still count. The store now
owns the list of terminal reasons, and isResumable reads it.

listActiveForHolder with includeSuspended returns only rows suspended for a
resumable reason, so its quota-sized read still covers every row a revocation
has to settle. Each holder keeps at most 500 terminal rows; a subscribe past
that deletes the oldest ones.

* feat(notifications): add status() to read whether pushes reach this browser

status() resolves 'on', 'off', 'blocked' or 'unavailable' without asking
anything. On a website it reads the notification permission, this
browser's subscription and the user's opt-in. Inside the desktop a new
pushStatus IPC, advertised as push-status, answers the browser's push
state, 'on' only while the app holds notifications:push.

* feat(notifications): disable() inside the desktop revokes the app's push permission

disable() did nothing inside the desktop. A new disablePush IPC,
advertised as disable-push, revokes the calling app's notifications:push
grant through the same route Settings uses, so its notifications stop
going out as pushes and a later enable() shows the permission dialog
again.

* feat(notifications): allow @ in a notification group, up to 128 characters

A group is an opaque display tag, hashed for the Web Push topic and used
as the notification tag, so it can carry identifiers such as an email
address.

* docs(notifications): say when a page with an older Puter.js holds a push back

* fix(notifications): let disable() win over an enable() still in flight

An enable() whose subscription reached the server after a disable() went
on to record the opt-in, so the next page load turned pushes back on. It
now rejects with push_verification_canceled and records nothing.

* docs(notifications): list push_verification_canceled and reword sentences that led with code

* fix(events): carry KV values through a share handle only at read or write

The delivery re-check now reads the share's level off the live handle along
with whether it still holds. A row on a watch share loses its includeValue for
that delivery, so its events name the key without the value; the owner's own
rows on the handle keep theirs. Decided per delivery, so raising or lowering a
share applies to subscriptions already made, and subscribing with includeValue
at watch is still accepted.

The live-updates recipe now shares at read, which its events need to carry
the score.

* fix(events): retry worker runs Puter could not complete without counting them

Invocations that never reached the handler (transport and dispatcher errors,
unmarked answers, failed or throttled deploys, no configured runtime, a bad
invoke key or missing token) now report an 'unavailable' outcome. So does a
handler that throws after one of its own puter.js calls got a 5xx, 429 or
network error from Puter's API, which the events runtime reports as
'platform-error'. Those runs back off like retriable ones, honor the answer's
retry-after up to the backoff ceiling, and no longer count toward the
consecutive-failure suspension. A run past the invoke timeout still counts.

* test(notifications): cover the pushNotifications resource and status() in the API suites

* test(gui): Allow on a batch that includes notifications:push turns push on

* fix(events): hold a share-handle row's backlog when its share can't be checked

The share-handle delivery check now tells a share that is gone (handle not
live, not the row's holder, identity gone, grant withdrawn) from one it can't
check right now (a lookup that throws, an owner who is suspended). Only the
first settles a queued row as permission_revoked and purges its backlog. The
second delivers nothing, leaves the row in service with its backlog, and sends
it to the back of the sweeper's line, so delivery resumes once the lookup
recovers or the owner is unsuspended. A revocation settle skips such a row and
leaves it to the delivery check. kvSharedRegionAuthorized returns null when
the permission check throws, and that answer is not cached.

* feat(events): update a persistent subscription's context in place

POST /events/subscriptions/update replaces a durable row's context, with the
same validation and 4 KB cap as subscribe, keeping its subId and backlog. The
row's owner region cache is rebuilt from the table and the generation bumped so
every region delivers the new value. It spends the subscribe call budget.

puter.events.update(subId, { context }) wraps it; null clears the context, and
a function handler this client registered for the subscription gets the new
ctx.

* fix(events): serve a fan-out's holders in turns and cap values per delivery

#route now orders an event's candidate rows before any cap applies: the
keyspace owner's rows first, then the other holders taking turns, one row per
holder per round, starting from a random holder each event. The filter
evaluation cap, the delivery cap and the gap markers all count in that order.

Values no longer drop for every delivery once more than 128 rows match or the
filter evaluation stops early. The first 128 deliveries that asked for the
value carry it, in serving order, and later ones carry the key alone.
EVENTS_KV_VALUE_OMIT_MATCHED_SUBSCRIPTIONS becomes
EVENTS_KV_VALUE_DELIVERIES_PER_EVENT. The caps themselves are unchanged.

* fix(email): file inbox mail as a delivery, not the request actor's write

storeInboxMessage and copyIntoInbox now run their filesystem writes with a
platformWrite context flag, and fs event dispatch leaves actingUserId unset
under it. Mail filed into an account's inbox from inside that account's own
request (an app mailing the signed-in user) is delivered with self: false, the
same as external ingress. Handler depth and viaWorker are still carried from the
actor.

* feat(notifications): raise the default daily app message limit to 1000

The per-day default for `app.message` goes from 300 to 1000 per user and
app, matching the daily push cap. The per-minute default stays at 30, and
`notificationAppMessageLimits` still overrides both.

* feat(notifications): look up an unseen notification by group

`notification` gets a nullable `group_key` column, a sha256 hex digest of
the group a row was written with, indexed on (user_id, app_uid, group_key).
`NotificationStore.create` takes a `group`, and `getUnseenByGroup` returns
the newest row an app wrote for a user under that group that is neither
shown nor acknowledged. Rows written before the column exist never match.

`updateValue` takes `onlyUnseen`, which also skips a shown row, and
`refreshCreatedAt`, which dates the row to now.

Migrations: sqlite 0098, mysql_mig_52, postgres_mig_41.

* feat(notifications): replace an app's unseen message in the same group

An `app.message` with a `group` now replaces the app's earlier notification
to the same user with that group while it is neither shown nor
acknowledged. The row keeps its uid and takes the new value and time. With
no group, or once the earlier one was shown or dismissed, it is a new
notification as before.

A replacement spends a per-minute slot but no per-day slot. If the earlier
row is marked between the lookup and the rewrite, the message is written as
a new notification and spends a day slot then.

`app.message` is groupable, so the replacement goes through
`notifyUpdate`. For types kept off the desktop, `notifyUpdate` skips the
desktop wire and dispatches the rewrite again under the same uid, so app
subscribers and receipts see it, and `notif.written` carries `updated`.

The driver's write path takes the recipient id rather than the actor, so
rate limits key on the recipient.

* feat(workers): report the app a worker runs as

workers.create now returns app_uid and app_name for the app its token is bound
to (null for a user-scoped worker), and list/get items carry app_name beside
app_uid from the app rows they already load. The dev center workers table shows
an App column, and the SDK typedefs and docs describe the fields and that a
sandboxed worker's notifications and pushes come from its sandbox app.

* feat(events): refuse handlers with free variables on REST publish

POST /events/handlers/publish and /publishAll now run the SDK's own
scanHandlerSource on each source before publishing and answer 400
events_handler_free_variable, naming the identifier. The backend imports the
module from src/puter-js; the build marks dist/src/puter-js as an ES module
package so the compiled backend can require it. Sources over the per-handler cap
are left to the store's size refusal rather than tokenized.

* docs(events): say Puter-side retries never suspend and stay within backlog caps

* fix(events): redeploy an events worker that answers bad-key

A script deployed before the internal secret rotated keeps the old invoke key,
so every invocation answered bad-key and nothing redeployed it. A bad-key answer
now goes through the same miss handler as a dispatcher miss (the deployer, with
its hourly throttle) and is retried once with the deployed header. A throttled
or failed redeploy stays 'unavailable' and backs off without counting.

* perf(events): check the deploy throttle before reading handler sources

EventsWorkerDeployer now reads the app's handler names and hashes first,
answers no-handlers or stale from those, and checks the hourly deploy throttle
before loading the sources and generating the worker. A throttled retry costs a
hash read and a counter bump instead of a full source read and build, and a
stale request still does not spend the throttle. The generated set is checked
against the script again in case it moved between the two reads.

* fix(workers): move a redeployed worker's row to the app it now runs as

Redeploying an existing worker under a different app minted the new app's
token but left subdomains.app_owner on the old one, so list/get and hot-reload
kept naming and minting for the old app. The redeploy now sets app_owner to the
binding #resolveWorkerAppBinding authorized (null for a user-scoped worker)
through a new SubdomainStore.setAppOwner, since app_owner stays read-only to
update patches.

* fix(workers): revoke the old binding's worker session on a rebind

A redeploy that binds a worker to a different app (or to none) now deletes the
owner's worker sessions under that name other than the one for the new binding,
through the same deleteWorkerSessionsByName path worker deletion uses (which
also announces the revocation and drops access-token grants). SessionStore's
deleteWorkerSessions takes an exceptAppUid filter for it, null meaning the
user-scoped session. The app_owner move and the revocation now both run only
after the new script deployed successfully, so a failed redeploy leaves the
live script, its token and the row on the old binding.

* feat(kv-share): store a notify flag on share handles

kv_share_handles gains a notify column, off by default, so every existing
share reads as not allowing notifications (sqlite 0099, mysql_mig_53,
postgres_mig_42). The store reads it on every row, including the live
handle cache and the holder listing, writes it on mint, and changes it
through update().

* feat(kv-share): let the owner turn notifications on for a share

POST /kv/shares and puter.kv.share() take notify, off by default. Leaving it
out of a re-share keeps the stored value, and turning it on or off counts as a
change, so it spends the mint budget. Turning it on for a holder who now
refuses the owner's shares is refused, like a raise or a new label.

The kv.share.received notice is sent only when a share starts carrying
notify: a new share made with it, or an existing one switched on. Its hourly
bound and the app-less namespace exclusion are unchanged.

The share response, the owner's listing and the holder's listing report
notify.

* feat(kv-share): resolve the other party of a share for a notification

KvShareService.resolveNotifyRecipient(actor, handle) returns the recipient
user id, app uid and handle for a notification one party of a share sends
the other through its handle. The handle must be live with an unsuspended
owner, the caller must be its owner or holder acting from the app whose data
it is, the share must have notify on, the holder's grant must still stand,
and the recipient must not refuse shares from the sender.

An unknown, retired or foreign handle, a caller who is not a party, and a
caller in another app all get subject_does_not_exist. The account itself gets
forbidden, a share without notify kv_share_notify_not_enabled, and a lookup
that fails service_unavailable. Once every check passes it spends one unit
from KV_SHARE_NOTIFY_LIMITS (30/min, 500/day per sender, recipient and app),
peeking both windows first so a refusal spends nothing.

* feat(notifications): hand a replaced notification to listeners again

A replacement now records `replaced_at` (epoch ms) on its row, added to the
same unreleased migrations as `group_key` (the sqlite file is renamed to
0098_notification-groups.sql). Its live event and its fetched copy both
carry `replaced: true` and use that time as `ts`, so the pair versions the
uid identically on both paths.

`onNotification()` dedupes on uid plus that version: an original counts as
version 0 and a replacement as its `ts`. A newer replacement is handed over
again with `replaced: true`, while a copy already handed over, a replay, or
an older state is dropped. Listeners started with `catchUp: false` still
get replacements of what was already there.

* fix(notifications): replace only the newest notification in a group

The group lookup takes the newest row an app wrote under the group and
returns nothing when that row was shown or dismissed, instead of falling
back to an older row that is still unseen.

The docs state the rule as it is: a grouped notification replaces the
newest one in its group unless that was shown or dismissed. Puter.js
marks neither, and the only thing that does is a tap on the push inside
the Puter desktop, which dismisses it.

* feat(notifications): notify the other party of a KV share through its handle

`app.message` takes `to: { handle }`. The driver validates the message,
then `to` must be an object with only a non-empty string `handle`, else
400. `KvShareService.resolveNotifyRecipient` checks the share and spends
the pair limit, and the message is written for the share's other party in
the share's app. The recipient's per-app limits and group replacement
apply to their own rows, and the push is billed to them through
`notif.written`.

A call with `to` answers with `{ uid }` only, so nothing about the
recipient's row reaches the sender. puter.js gets the
`NotificationRecipient` type for `to`.

* docs(notifications): document notifying the other side of a KV share

notify.md covers `to: { handle }`: who can be reached, the errors, the
recipient's limits plus the per-pair share limit, the uid-only return and
that the recipient pays for pushes. push.md and rate-limits-and-quotas.md
point at the share path. The chat notification recipe sends through each
share's handle and keeps the per-member handler only for members who need
to reach each other; the alert recipe says when its handler is the right
fit.

* fix(notifications): reveal nothing to the sender of a notification through a share

A call with `to: { handle }` answers with an empty object, and puter.js
resolves it with no value: a uid would show whether the recipient's last
notification in a group was replaced. `notify()` gets one overload per
form, and `ShareNotificationInput` is exported.

Over the per-pair share limit or the recipient's own limits, such a call
gets the same 429 `too_many_requests` with the same generic message, so the
sender can't tell which limit it hit.

* fix(notifications): serialize grouped app messages per group

Grouped app.message sends take a Redis lock on (recipient, app, group) around the lookup and the replace-or-insert, so concurrent sends to an empty group write one row and spend one day slot. A lock still busy after the wait, or an unreachable Redis, sends unlocked as before. Sends without a group take no lock.

* fix(events): attribute Puter API failures to the invocation that saw them

The events worker runtime counted Puter API failures on the cached per-token client, so a concurrent invocation on the same token could answer platform-error for its own unrelated throw. A cached client now serves one invocation at a time and records failures and retry-after on that invocation; an invocation overlapping another on the same token gets its own client, and idle clients stay cached per token.

* fix(events): drop KV values from a queued backlog once its share is at watch

A queue delivery is stored with its value. Every hand-out of a stored
entry (backlog drain to a socket or another region, the worker, and a
declined delivery passed to the worker) now re-reads the share's level
and removes the value at watch. A share that can't be checked still
holds the backlog.

* fix(events): return notifications replaced behind the fetch cursor

The notification fetch cursor now holds the last row id and the last
(replaced_at, id) it returned. A read from it merges two indexed reads:
rows inserted after the id, and rows up to the id replaced after that
mark. A replacement made while a client was away therefore comes back
on its next catch-up. Adds idx_notification_replaced on (user_id,
audience, app_uid, replaced_at).

Daniel Salazar 179ad990d6 feat(events): simplify onPersistent delivery (#4395)
* feat(events): simplify onPersistent delivery

Replace delivery/targets with a boolean single. Without single, every
event runs the app's published handler in its events worker and is also
sent to every connected client; the server no longer routes between the
two. single keeps leasing each event to one consumer that acks.

delivery: 'single' | 'broadcast' is still accepted and targets is
ignored. Stored rows are read by their delivery column alone.

* docs(events): compare onLocal, onPersistent and single

* feat(events): rename single to queue

onPersistent({ queue: true }) is the work-queue mode: each event goes to
one consumer at a time and is offered again until acknowledged.
delivery: 'single' is still accepted as an alias, and subscription
objects report queue instead of single.

The docs explain the three modes (onLocal, default onPersistent, queue)
and each events recipe says which one it uses and why.

* docs(events): retries are the only repeat for a queued event

* feat(events): queue deliveries fall through to the worker on decline

A queued delivery gets one socket attempt under a 15 s lease instead of
two 60 s ones. A client with no handler for it, or whose handler fails,
sends events.nack and the worker takes it without waiting for the lease.
Declines are relayed to the region holding the lease like acks are, and
a decline for a lease that is no longer the client's is ignored.

* feat(events): drop thrown errors, retry only temporary ones

A queued handler that throws now drops the event and counts one failure
toward the pause. Network errors, timeouts, rate limits, 5xx responses
and errors thrown with retry: true are retried with the existing
backoff. One classifier is shared by puter.js and the events worker
runtime, which inlines it at build time. A dropped event is billed once,
like a completed one. ack() remains as an optional early release.

* docs(events): queued events reach every tab with a handler

Daniel Salazar b784b51cf3 fix: harden the events stack for flag-on (#3752)
* fix: harden events dispatch, single delivery and KV share handles

Dispatch: a filtered subscription used the anchor path stored at subscribe
time, so renaming or moving the anchor folder silently ended its deliveries;
dispatch now resolves the anchor's live path from the event's own ancestor
chain. A move out of a watched folder now reaches that folder's subscribers,
with `from` only for rows that watched the source side. Gap markers are
authorized like deliveries and coalesced per subscription and subject instead
of fanning per lost event. Session subscriptions: the per-socket cap decides
on the write, not before it; an orphaned watched-set token heals on refresh;
durable rows keep their watch window when a session subscribe touches the
same keys. `self` is false when the acting user is unknown.

Single delivery: a subscription in backoff or suspended with a backlog pinned
the sweeper's head and starved everyone behind it — the sweep now defers it.
Only a settled handler run bills a delivery. A socket-only account row no
longer wedges after two attempts nobody received. The lease is twice the
handler timeout; remote candidates have their own attempt counter; the region
depth reconcile runs once a minute region-wide with a bounded scan.

KV share handles: a grantee no longer sees the owner's namespace and absolute
prefix on the subscribe answer or listing, nor in the delivery token; revoking
a wider handle retires the handles it covers; minting the same handle twice
returns the existing one, after the delegation check; a row whose event
cannot be re-based onto its handle is dropped rather than delivered raw.

* fix: presence survives replication, long sessions and region churn

One presence item per (user, app) with per-region map fields lost a region
whenever two regions joined inside the replication window, and nothing ever
put it back. Presence is now one item per (user, app, region): each region
writes only its own, a leave or repair retires it conditionally on its own
write stamp, and a read is a prefix query. Items carry a 48 h ttl refreshed by
a claim-gated write off the existing socket renew path, at most once per
12 h, so a tab that stays connected keeps its region in the row. A region
that answered "no socket" or completed a leave releases a shared pin, so a
reconnect on another node rejoins and a flapping client cannot force a
replicated write per cycle. Cached rows expire after a minute; unaddressable
region names are filtered and pruned; relayed acks settle under a bounded
concurrency; the forward queue is bounded in bytes as well as items.

* feat: indexes for the event_subscriptions hot queries

Handler publish, remove and listing, and the hourly expiry and suspension
sweeps, all scanned `event_subscriptions`. Adds (app_uid, handler_name),
(expires_at) and (suspended_at, id), guarded on every engine. Existing
migrations: the postgres widens are now guarded so a boot does not take an
exclusive lock for a no-op, the kv_share_handles grantee FK gets an index,
the sqlite notification rebuild is transactional and idempotent.

* fix: notification writes go through the registry

The driver's `create` bypassed the type registry, producing uncatalogued
rows with no size bound; it now requires a registered type, caps the payload,
and answers 400 rather than 500 for a bad one. `mark_acknowledged` emits the
ack other tabs listen for, and only when a row was actually changed.

* fix: the handler scanner, unsubscribe, and the in-tab handler environment

The free-variable scanner skipped arrows inside a declaration's initializer,
so `const ids = event.items.map(x => x.id)` was refused, and treated a name
after a comma in a nested initializer as bound, so a real free variable slipped
through to fail on first delivery. `unsubscribe()` now drops the durable
routing entry so the events socket can close. A broadcast handler running in
the tab gets `user` and `fetch` like the worker gives it. `single` without
a handler name is refused before the round trip.

* docs: events limits, error codes and the background-workers section

Retention is deployment-configured rather than a fixed 14 days, and the
template no longer ships it armed. Documents `events_terminal`, the two
per-event gap reasons, the subject length and listing caps, the `from` field
on moves, and the handle-relative anchor. The sessions manager hides the
background-workers section when the server has none to show.

* feat: a background handler acts as the app does for its user

A handler's `user` was a five-minute access token scoped to the subscription's
`list` grant, which could stat the changed file but not read it, and could
not reach the app's KV or AppData — so an app told that a file was written
could do nothing with it. It now runs with the same authority the app has for
that user in a tab: an app-under-user worker session, one row per (user, app)
named `events:handlers`, visible and revocable in the sessions list. The
`events:background` consent is what authorizes running it unattended, and is
re-checked before every mint.

The wider token exposed two things: puter.js opens a filesystem socket the
moment it has a token, which would have parked the isolate in the app's own
delivery room and steered deliveries at it; the events client now opts out of
sockets (and the per-open bookkeeping) before construction, and is memoized
per token in the isolate. And four filesystem operations assumed a socket
exists; they no longer do.

Daniel Salazar f30baa2a1c feat: the per-app events worker runtime (#3697)
* feat: bake published handlers into a generated events worker

* feat: deploy and address the per-app events worker behind a flag

* test: single delivery end to end through a real local worker

* feat: events workers run their own runtime, in their own namespace

An events worker was being deployed as an ordinary worker: default dispatch
namespace, a `subdomains` row, the router preamble, and an app-scoped worker
token baked in. The public dispatcher resolves any script in that namespace
straight off the hostname, so the worker answered at `<name>.puter.work`, and
the only thing in front of it was an unguessable name plus a check that a
`puter-auth` header was present — which the router never validates. Anyone who
learned the hostname could run an app's handlers with a body of their choosing,
in an isolate holding the owner's token as `me`.

Instead:

- Handlers run on their own runtime (`src/worker/src/events-runtime.js`), which
  provides no `router` and no `me`, owns the single invoke route, and hands a
  handler only `{ event, ctx, user, fetch, ack }`. `user` is built from the
  invocation's delivery token, so a handler acts as the subscriber whose
  delivery it is and nothing wider. The preamble build emits one bundle per
  runtime; the shared half of the template is now included by both.
- The deploy target carries the runtime to prepend, the source to deploy, and
  whether to mint a worker token at all, so an events worker deploys into the
  `events` dispatch namespace from generated source with no token binding, no
  `subdomains` row, and no claim on the owner's worker quota or worker list.
- An invocation carries a key derived from the deployment secret and the script
  name, bound as a secret and checked in constant time inside the isolate,
  which reads it once and drops it before handler code runs.
- Scripts are named after the handler set they contain, so publishing writes
  rows and deploys nothing: a set is deployed the first time a delivery needs
  it, and a changed set is a new script rather than an overwrite of a running
  one. Publish responses keep the shape they had before the runtime existed.
- Invocations reach a worker only through the events dispatcher, which has no
  zone route and requires the internal secret; the backend's own deploy path is
  the rehydrate route the dispatcher calls on a namespace miss. Locally there is
  no dispatcher, so the controller hands the service an in-process transport
  that deploys on miss itself.

The SDK stops allowlisting `puter` as a handler global — a handler that reaches
for an ambient SDK is now refused at publish time, naming `user` instead, rather
than passing the scan and failing on its first delivery.

Requires `events.workerNamespace`, `events.dispatcherUrl` and
`events.internalSecret`; without them nothing is addressable and background
deliveries stay retriable, as they did with the runtime off.

* fix: a handler's delivery token gets through the read routes

An events handler acts as the subscriber through the access token its
invocation carried, but every FS read route refused scoped access tokens
outright, so `user.fs.stat(event.path)` — the design's own example — answered
403 inside the worker. The read-side routes now admit them; the ACL each
handler already runs intersects the token's grant with its issuer's, which is
the check that keeps a token to what it was minted for. The end-to-end suite
asserts the stat from inside the isolate.

* fix: shorthand-method handlers publish as functions

`{ ingest({ event }) { … } }` stringifies without the `function` keyword, so
its source is not an expression and the events worker baked it as a broken
stub — every delivery a retriable 500 until the subscription suspended, with
nothing at publish time to say why. The SDK now gives a shorthand method the
keyword before hashing and sending; getters, setters and computed names are
left for the server-side check to refuse.

* feat: an app's events worker is listable and destroyable

An app with published handlers has an events worker, and hosted deployments
bill it monthly per app, so its owner needs to see it and be able to take it
down. The core announces the lifecycle on the bus — `events.worker.create`
when an app's first handler is published, `events.worker.destroy` when its last
one goes — with the owner as the actor, so pricing can plug in from outside.
`GET /events/workers` lists the caller's workers (paginated, with the script
each set deploys as) and `POST /events/workers/destroy` removes every handler
of an app under the same owner scoping as the handler routes, suspending the
subscriptions bound to them. `puter.events.workers.list/destroy` in the SDK,
a docs page, and a 5 MB cap on an app's combined handler source
(`events_worker_too_large`) so a set that publishes can always deploy.

* fix: harden the events worker runtime for production

- A 4xx is terminal only when it carries the handled marker the runtime (and
  the dispatcher) stamp on every answer that came from a script; an unmarked
  4xx — an edge 404 for a wrong dispatcher hostname, a WAF page — stays
  retriable and is logged, once per script per minute, with the runtime's
  reason header.
- Script names are scoped to this backend's exposed API origin, so two
  backends sharing a namespace never resolve one script with the wrong
  endpoint binding or key. Shape unchanged.
- Each handler is validated in the exact context it is emitted into and the
  whole generated file is compiled once; a source that would break the script
  marks every handler broken instead of deploying a SyntaxError.
- Locally, events scripts live under their own registry key: the public local
  worker host cannot reach them and an ordinary worker cannot take their name.
- A suspended or deleted app owner stops invocations; deploys are throttled
  per app per hour; in-flight deploys are keyed by app and script; the
  upstream deploy call times out; the generated source is size-capped with a
  margin over the publish cap; boot fails when the runtime is on but its
  preamble is not built. Byte-length secret compare, appUid shape check,
  dispatcher URL prefix preserved, wider connection pool.

* feat: background workers are listed in the sessions manager

A user paying for an app's events worker needs somewhere to see it and take it
down. The sessions manager gets a section listing the apps that run event
handlers in the background, with a Destroy action that removes their published
handlers.

* fold in v1 fixes from origin/main into v2 equivalents

Re-applies the v1 fixes that landed on origin/main into their v2
counterparts since the v1 files were deleted on DS/wip during the v2
migration. v1 commits referenced below.

- SQLBatcher: flush immediately when queue hits maxBatchSize instead
  of racing the timer (v1 12f48238).
- RedisClient: drop maxRetriesPerRequest from 2 to 1 to shrink failure
  window (v1 b6776ab4).
- ChatCompletionDriver: default minimumCredits to 1 when unset/zero so
  zero-cost precheck doesn't auto-pass (v1 36bd6073).
- OpenAiImageProvider: add gpt-image-2 support — open-ended size rules,
  token-based cost estimator, arbitrary-size normalizer, isGpt prefix
  broadened to gpt-image- (v1 f14f1bf4). models.ts auto-merged via
  rename detection.
- AppStore: bump row cache TTL from 5m to 24h (v1 6b3196ed).

Not ported: v1 app-object Redis cache (bdfa12b5/b886dde3) — v2's
#toClient recomputes filetype_associations/created_from_origin per
read; adding a second cache layer is a larger change for a follow-up.
