feat: show daemon config in 'bd daemon --status' output

Add auto-commit, auto-push, local mode, sync interval, and daemon mode
to the status output when querying a running daemon.

This helps users understand the current daemon configuration without
having to check logs or remember what flags were used at startup.

Changes:
- Add config fields to StatusResponse in protocol.go
- Add SetConfig() method to Server for daemon to set its config
- Update handleStatus() to include config in response
- Update showDaemonStatus() to query and display config via RPC
- Add comprehensive test coverage for new functionality
