Code Review: bugfix/linger

This is a solid refactoring that simplifies the SessionManager and improves error handling.

✅ Strengths

1. SessionManager Simplification - Removed complex linger timeout logic, making message handling more straightforward. The event-driven architecture is clean with excellent comments.

2. Logger Enhancement (src/utils/logger.ts:240-250) - Smart handling of Error objects with proper instanceof checks. Preserves stack traces in DEBUG mode, which is very helpful for debugging.

3. DatabaseManager Cleanup (src/services/worker/DatabaseManager.ts:30-32) - Removed background backfill on startup and made ChromaSync lazy-loaded. Good performance improvement.

🔍 Potential Issues & Questions

1. SessionManager Message Iterator (src/services/worker/SessionManager.ts:409-443)
The recheck pattern at line 431 handles race conditions well, but consider adding a comment explaining why this recheck is critical.

2. Project Refresh Logic (src/services/worker/SessionManager.ts:65-76)
Questions: How often does this happen? Should we track metrics on this to identify upstream timing issues?

3. Error Formatting
The formatting differences between formatData() and log() appear intentional for spacing.

⚡ Performance

Positive changes across the board - removing background backfill and lazy ChromaSync init eliminate unnecessary work.

🧪 Testing

Consider adding tests for: message iterator abort behavior, project refresh logic, and Error object formatting.

🎬 Recommendation

APPROVE with minor suggestions

Quality refactoring. Issues identified are minor documentation questions rather than bugs.

Great work! 🚀
