 * Main API hook for A2UI. Provides methods to process messages
 * and access surface state.
 *
 * Note: This hook subscribes to state changes. Components using this
 * will re-render when the A2UI state changes. For action-only usage
 * (no re-renders), use useA2UIActions() instead.
 *
 * @returns Object with message processing and surface access methods
 *
 * @example
 * ```tsx
 * function ChatApp() {
 *   const { processMessages, getSurface } = useA2UI();
 *
 *   useEffect(() => {
 *     const ws = new WebSocket('wss://agent.example.com');
 *     ws.onmessage = (event) => {
 *       const messages = JSON.parse(event.data);
 *       processMessages(messages);
 *     };
 *     return () => ws.close();
 *   }, [processMessages]);
