731f40da34 Fix FileWatcher robustness issues (bd-71) 
- Fix Debouncer race condition with sequence numbers to prevent double-fire
- Add parent directory watch to catch file creates/renames
- Add .git/HEAD watch for branch change detection
- Implement retry/backoff (50-400ms) for re-establishing JSONL watch
- Handle Create/Chmod events in addition to Write
- Add .git/HEAD polling in polling mode
- All 18 debouncer and watcher tests pass

176dc0d601 Fix bd-66: Add robust polling fallback for file watcher 
- 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.

781e300d33 Add event-driven daemon architecture (Phase 1 foundation) 
- Add fsnotify dependency for file watching
- Create daemon_debouncer.go: batch rapid events (500ms window)
- Create daemon_watcher.go: monitor JSONL and git refs changes
- Create daemon_event_loop.go: event-driven sync loop
- Add mutation channel to RPC server (create/update/close events)
- Add BEADS_DAEMON_MODE env var (poll/events, default: poll)

Phase 1 implementation: opt-in via BEADS_DAEMON_MODE=events
Target: <500ms latency (vs 5000ms), ~60% CPU reduction
