feat(gateway): add --install-daemon to run picoclaw as system service

Add daemon management flags to the gateway subcommand using
kardianos/service, supporting Linux (systemd), macOS (launchd),
and Windows (SCM).

New flags:
  --install-daemon    Install as system service
  --uninstall-daemon  Uninstall system service
  --start-daemon      Start the installed service
  --stop-daemon       Stop the installed service
  --daemon-status     Show service status

+
+PicoClaw は [kardianos/service](https://github.com/kardianos/service) を使用してシステムサービスとしてインストールできます。**Linux (systemd)**、**macOS (launchd)**、**Windows (SCM)** に対応しています。
+
+```bash
+# システムサービスとしてインストール（Linux では root/sudo が必要）
+sudo picoclaw gateway --install-daemon
+
+# サービスを起動
+sudo picoclaw gateway --start-daemon
+

+### Run as System Service (Daemon)
+
+PicoClaw can be installed as a system service using [kardianos/service](https://github.com/kardianos/service), which supports **Linux (systemd)**, **macOS (launchd)**, and **Windows (SCM)**.
+
+```bash
+# Install as a system service (requires root/sudo on Linux)
+sudo picoclaw gateway --install-daemon
+
+# Start the service
+sudo picoclaw gateway --start-daemon
+
+# Check service status
+picoclaw gateway --daemon-status
+
+# Stop the service
+sudo picoclaw gateway --stop-daemon
+
+# Uninstall the service
+sudo picoclaw gateway --uninstall-daemon
+```
+
+> [!NOTE]
+> The service runs as the user who installed it, so it can access `~/.picoclaw/config.json`.
+> To install with debug logging enabled, use `sudo picoclaw gateway --install-daemon --debug`.
