Daemon Management

Tools

• yao_daemon_start, Start a long-running service. Always runs in background; returns daemon_id immediately.
• yao_daemon_list, List daemons. Supports --status filter and --limit/--offset pagination.
• yao_daemon_status, Get full details for a daemon (daemon_port, daemon_url, started_at, daemon_restarts).
• yao_daemon_stop, Stop a running daemon.
• yao_daemon_restart, Restart a daemon (preserves the same ID, increments daemon_restarts).
