Daniel Salazar 279bb8beb6 fix(events): KV share handle subscription follow-ups (#4434)
* fix(events): bound share-handle session rows by the per-connection cap

The count across a holder's connections also counted connections that
had dropped but weren't reaped yet (a crashed node, a deploy, a network
blip the server hasn't noticed), so resubscribes after a reconnect could
be refused with `events_subscription_limit`. Rows made through a share
handle now count toward the 50-per-connection cap like any other, and
with the open-connections cap per account that bounds what one holder
can put in the owner's keyspace.

The handle index stays for ending rows on retire. Rows are added to it
with the row itself and taken out when the row is dropped, and members
whose row is gone are cleared when a retire reads it.

* fix(events): keep a retire's durable settle running if ending sessions fails

Ending a retired handle's session subscriptions reads Redis. A failure
there is now logged and the durable suspension that follows still runs,
so those rows' backlogs are still purged.

* perf(events): ask once per handle when a refresh screens rows, and share handle reads

A socket refresh asks whether a share handle still stands once per
handle, holder and app, rather than once per row: rows through one
handle share its grant. Concurrent cache misses on one handle share a
single read; a forget drops the shared read so later callers start a
fresh one.

* fix(events): keep a loose cap on subscriptions through one share handle

Without a count across connections, a holder could put up to 20,000 rows
in the owner's keyspace (50 per connection, 400 connections), each one
evaluated on every owner write. The cap is back at 1,000 per holder per
handle, far above what connections that dropped without being reaped
leave behind. The index is only read row by row once it's past the cap.

Getting Started

💻 Local Development

git clone https://github.com/HeyPuter/puter
cd puter
npm install
npm start

→ This should launch Puter at http://puter.localhost:4100

To run this checkout with Docker, follow Building from source. Create a local docker-compose.override.yml to select the local build; keeping these settings out of docker-compose.yml avoids conflicts when pulling updates and keeps local configuration out of pull requests.
