// Command lmvpnd is the privileged LMVPN daemon. It owns the WebSocket
// transport, TUN device, and routing. It receives commands from the GUI
// over an IPC unix socket and broadcasts state/stats events back.
//
// This is a separate binary from the GUI (lmvpn) to avoid loading Fyne
// (and its locale/font initialisation) in the root process.
//
// Daemon flags:
//
//	--user-home <path>  invoking user's home dir (for log/data paths)
//	--uid <int>         invoking user's UID (chown IPC socket + logs)
//	--gid <int>         invoking user's GID
