Single-instance + openclaw:// deep links (openclaw://dashboard opens and
connects the dashboard; the tiny URL contract is routed entirely in Rust), a
Start at Login tray toggle (tauri-plugin-autostart, default off), native
notifications for update-ready/update-available when the window is unfocused,
and window-state persistence (canvas window excluded). All official Tauri v2
plugins; cross-platform deps so the macOS/Windows test builds keep compiling.
