Phase 2: Add client auto-detection in bd commands (bd-112)

- Add daemon client infrastructure to main.go with TryConnect logic
- Update PersistentPreRun to detect daemon socket and route through RPC
- Add --no-daemon flag to force direct storage mode
- Update all commands (create, update, close, show, list, ready) to use daemon when available
- Maintain backward compatibility with graceful fallback to direct mode
- All commands work identically in both daemon and direct modes

Part of bd-110 daemon architecture implementation.
