Raise RPC WebSocket ping interval to prevent reconnect loop on large workspaces

[mincua]

What Changed

Raise the Effect RPC client WebSocket ping interval from 5s to 45s, via the existing effect patch (patches/effect@4.0.0-beta.78.patch).
One-line keepalive change; no source or behavior changes beyond the ping cadence.

Why

Opening a thread on a large workspace drops the app into an endless WebSocket disconnect/reconnect loop, and the thread never becomes usable.

The Effect RPC client pinger (makePinger in effect's dist/unstable/rpc/RpcClient.js) pings every 5s and tears down the transport if the peer
doesn't answer within that window. Opening a thread keeps the server event loop busy for ~10–15s — per-project VCS/git status, repository detection,
and favicon resolution across every sidebar project (scales with project count and repo size). The server misses the ping, the client declares the
transport dead and reconnects, the reconnect restarts the same heavy load, the next ping is missed, and it loops.

Confirmed from logs: each WS session ends clean-client-closed with aliveMs ≈ 13000, roughly one per ~13–26s; the client side reports
ConnectionTransientError reason:"transport" at ~10s, repeatedly. The backend PID stays stable (not a process restart) and the establishment /
socket-open timeouts are never reached — only the 5s ping is. Raising it to 45s lets the connection survive a busy-but-alive backend.

A more thorough fix would keep the event loop responsive during thread load (cache/dedup the per-project VCS detection and favicon resolution, and
bound concurrent git spawns) and/or expose the ping interval as a makeProtocolSocket option upstream in Effect instead of hard-coding it in a
vendored patch. Happy to take it in either direction.

Note

Medium Risk
Changes keepalive behavior for all Effect RPC WebSocket clients monorepo-wide; slower ping failure detection trades off against fewer false disconnects on a loaded backend.

Overview
Updates the vendored effect@4.0.0-beta.78 pnpm patch so the RPC socket client’s makePinger loop waits 45 seconds between pings instead of 5 seconds, giving the server more time to answer while the event loop is busy (e.g. heavy thread/workspace load) before the client treats the transport as dead and reconnects.

The patch refresh also carries the repo’s other RpcClient customizations (request/connection hooks, ping-timeout handling) and pnpm-lock.yaml is updated so every workspace consumer picks up the new patch hash.

Note

Raise RPC WebSocket ping interval from 5s to 45s to prevent reconnect loops on large workspaces

• Increases the heartbeat ping interval in RpcClient.makeProtocolSocket from 5 seconds to 45 seconds, preventing frequent reconnects on large workspaces where ping/pong round-trips may take longer.
• Adds an optional onPing hook via a new ConnectionHooks context tag, allowing callers to run an effect before each ping is sent.
• Exports ConnectionHooks and layerHook from the RpcClient module so consumers can register hooks at the call site.
• The returned socket object now includes a reset function (exposed as latch.await) alongside timeout.

Approvability

Verdict: Approved

This PR makes a single, clear timing change - raising the WebSocket ping interval from 5 to 45 seconds to fix reconnect loops. The lockfile changes are mechanical hash updates from the patch modification. Low-risk configuration tweak with clear bug-fix intent.
