- Detect fsnotify.NewWatcher() errors and auto-fallback to polling mode
- Add BEADS_WATCHER_FALLBACK env var to control behavior (default: enabled)
- Poll every 5 seconds with comprehensive change detection:
- Track file existence, size, and mtime to catch all changes
- Handle file disappearance/reappearance correctly
- Trigger on file recreation even with older timestamps
- Fix goroutine leak: Close() now stops background goroutines via cancel context
- Tighten git refs filtering to only trigger for events under .git/refs/heads
- Trigger after successful JSONL rewatch on rename/remove events
- Improve logging to show actual poll interval in warnings
All tests passing.
