## Bug Fixes

### Zombie Observer Prevention (#856)

Fixed a critical issue where observer processes could become "zombies" - lingering indefinitely without activity. This release adds:

- **3-minute idle timeout**: SessionQueueProcessor now automatically terminates after 3 minutes of inactivity
- **Race condition fix**: Resolved spurious wakeup issues by resetting `lastActivityTime` on queue activity
- **Comprehensive test coverage**: Added 11 new tests for the idle timeout mechanism

This fix prevents resource leaks from orphaned observer processes that could accumulate over time.
