Implemented bd-150: Improve daemon fallback visibility and user feedback
- Added DaemonStatus struct to track connection state
- Enhanced BD_DEBUG logging with detailed diagnostics and timing
- Added BD_VERBOSE mode with actionable warnings when falling back
- Implemented health checks before using daemon
- Clear fallback reasons: connect_failed, health_failed, auto_start_disabled, auto_start_failed, flag_no_daemon
- Updated documentation
Implemented bd-151: Add version compatibility checks for daemon RPC protocol
- Added ClientVersion field to RPC Request struct
- Client sends version (0.9.10) in all requests
- Server validates version compatibility using semver:
- Major version must match
- Daemon >= client for backward compatibility
- Clear error messages with directional hints (upgrade daemon vs upgrade client)
- Added ClientVersion and Compatible fields to HealthResponse
- Implemented 'bd version --daemon' command to check compatibility
- Fixed batch operations to propagate ClientVersion for proper checks
- Updated documentation with version compatibility section
Code review improvements:
- Propagate ClientVersion in batch sub-requests
- Directional error messages based on which side is older
- Made ServerVersion a var for future unification

- Add OpHealth RPC operation to protocol
- Implement handleHealth() with DB ping and 1s timeout
- Returns status (healthy/degraded/unhealthy), uptime, cache metrics
- Update TryConnect() to use health check instead of ping
- Add 'bd daemon --health' CLI command with JSON output
- Track cache hits/misses for metrics
- Unhealthy daemon triggers automatic fallback to direct mode
- Health check completes in <2 seconds

- Added per-request storage routing in daemon server
- Server now supports Cwd field in requests for database discovery
- Tree-walking to find .beads/*.db from any working directory
- Storage caching for performance across requests
- Created Python daemon client (bd_daemon_client.py)
- RPC over Unix socket communication
- Implements full BdClientBase interface
- Auto-discovery of daemon socket from working directory
- Refactored bd_client.py with abstract interface
- BdClientBase abstract class for common interface
- BdCliClient for CLI-based operations (renamed from BdClient)
- create_bd_client() factory with daemon/CLI fallback
- Backwards-compatible BdClient alias
Next: Update MCP server to use daemon client when available
