Create jobkit-daemon crate with generic daemon infrastructure: - event_log: JSONL append with size-based rotation - socket: Unix domain socket RPC client and server with signal handling - status: JSON status file read/write Migrate daemon.rs to use the library: - Worker pool setup via Daemon::new() - Socket loop + signal handling via Daemon::run() - RPC handlers as registered closures - Logging, status writing, send_rpc all delegate to library Migrate tui.rs to use socket::send_rpc() instead of inline UnixStream. daemon.rs: 1952 → 1806 lines (-146), old status_socket_loop removed. tui.rs: socket boilerplate removed.
