- Fix streaming timeout: use AbortController for connection-only timeout
instead of AbortSignal.timeout() that kills active SSE streams
- Fix fetchViaCurl: stream body via ReadableStream instead of buffering
entire response in memory
- Fix JWT/aichat race condition: add Promise dedup to prevent concurrent
bootstrap calls (10 requests = 1 bootstrap, not 10)
- Fix ACTIVE_READERS memory leak: auto-remove readers on stream completion
- Fix WebSocket backpressure: log warning when client buffer exceeds 1MB
- Add SSE heartbeat/keepalive: send ': keepalive' every 15s to prevent
LB/proxy timeout during AI thinking
- Fix SSELineBuffer: graceful overflow handling (warn + discard instead
of throwing error that crashes stream)
- Fix transformStream tight loop: yield to event loop after each chunk
to prevent starvation
- Fix fetchViaCurl process cleanup: use SIGKILL + proper timeout cleanup
- Add retry on 502/504: retry transient server errors before returning
to caller (both fetchWithRetry and fetchWithSessionRetry)
