Daniel Salazar 92af0ef634 fix(ai): backpressure and upload budget on the realtime relay
Neither direction applied backpressure: a client that stopped reading
grew a queue up to 64 MiB, and a client streaming 16 MiB frames was read
and forwarded as fast as it could send. A few such sockets pinned the
event loop and pushed RSS past 1 GB.

Each side now stops reading the other once 1 MiB is queued toward it,
and a client that keeps the upstream paused for 30 s is closed. Client
uploads are budgeted per session (1 MiB/s sustained, 16 MiB burst,
realtime.maxClientBytesPerSecond), pre-open buffering pauses reads at
1 MiB instead of rejecting at 32 MiB, and clients get a 30 s ping so
half-open sockets release their upstream and slot. Upstream frames use
a zero mask and skip UTF-8 validation, which the relay never needed.

The stats line gains elu. tools/realtime-stress gains abuse.mjs and a
runbook phase for event-loop abuse.

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.
