 * useApp(windowId) - the single entry point for App components to interact with the system.
 *
 * After Window.jsx injects windowId via cloneElement, the App component only needs to call this hook,
 * without directly importing any Context.
 *
 * Usage:
 *   function MyApp({ windowId, ...props }) {
 *     const api = useApp(windowId);
 *     await api.dialog.alert({ title: 'Tip', message: 'Hello' });
 *   }
