/**
* Base hook for A2UI components. Provides data binding, theme access,
* and action dispatching.
*
* @param node - The component node from the A2UI message processor
* @param surfaceId - The surface ID this component belongs to
* @returns Object with theme, data binding helpers, and action dispatcher
*
* @example
* ```tsx
* function TextField({ node, surfaceId }: A2UIComponentProps<Types.TextFieldNode>) {
*   const { theme, resolveString, setValue } = useA2UIComponent(node, surfaceId);
*
*   const label = resolveString(node.properties.label);
*   const value = resolveString(node.properties.text) ?? '';
*
*   return (
*     <div className={classMapToString(theme.components.TextField.container)}>
*       <label>{label}</label>
*       <input
*         value={value}
*         onChange={(e) => setValue(node.properties.text?.path!, e.target.value)}
*       />
*     </div>
*   );
