fb65163692 fix: address critical resource leaks and error handling issues (#327)
* fix: address critical resource leaks and error handling issues

Fixes 5 critical and high-priority issues identified in codebase analysis:

1. bd-vavh: Fix row iterator resource leak in recursive dependency queries
   - Move defer rows.Close() to execute on all code paths
   - Previously leaked connections on scan errors
   - Location: internal/storage/sqlite/sqlite.go:1121-1145

2. bd-qhws: Configure database connection pool limits for daemon mode
   - Set MaxOpenConns to runtime.NumCPU() + 1 for file-based databases
   - Prevents connection exhaustion under concurrent RPC load
   - Only affects daemon mode (long-running server)
   - Location: internal/storage/sqlite/sqlite.go:108-125

3. bd-jo38: Add WaitGroup tracking to FileWatcher goroutines
   - Track goroutines with sync.WaitGroup for graceful shutdown
   - Wait for goroutines to finish before cleanup in Close()
   - Prevents race condition on debouncer access during shutdown
   - Location: cmd/bd/daemon_watcher.go (Start, startPolling, Close)

4. bd-2d5r: Fix silent error handling in RPC response writing
   - writeResponse now returns errors instead of ignoring them
   - Prevents sending partial JSON and client hangs
   - Closes connection on marshal/write errors
   - Location: internal/rpc/server_lifecycle_conn.go:227-246

5. bd-zqmb: Fix goroutine leak in daemon restart
   - Add 10-second timeout to daemon Wait() goroutine
   - Kill process if it doesn't fork within timeout
   - Prevents goroutine accumulation on restart failures
   - Location: cmd/bd/daemons.go:250-268

All changes follow Go best practices and maintain backward compatibility.

* Add feature request for .beads/README.md generation during init

Created bd-m7ge to automatically generate a promotional/documentation
README in the .beads directory when running 'bd init'. This will help
advertise Beads in open source repositories and provide quick reference
documentation for developers using AI coding agents.

The README will include:
- Brief explanation of Beads (AI-native issue tracking)
- Link to steveyegge/beads repository
- Quick reference of essential commands
- Compelling messaging to encourage adoption

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
