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.
