### Non-breaking notes
- `@astrojs/node` sharp feature warning in logs — harmless
- `ChatReply.tsx` and `NewChatBar.tsx` are unused (not imported anywhere)
- `/code/api/threads` doesn't include a `heartbeats` field, but `use-threads.ts` handles this gracefully with a fallback

No rebuild or restart was needed.
