The truncation logic and error handling added in e1d3c2b7 (Dec 4, 2025)
was lost when message handling was refactored from slack.ts to main.ts.
Changes:
- Add try/catch to all Slack message functions (respond, replaceMessage,
respondInThread, setTyping, setWorking)
- Truncate main messages at 35K chars (Slack limit 40K)
- Truncate thread messages at 20K chars
- Add helpful user-facing notes when truncation occurs
- Log Slack API errors as warnings instead of crashing
Fixes: msg_too_long API errors causing process crash
