/**
 * @class AIGUIController
 * @brief High-level controller for AI-driven GUI automation with vision feedback
 * 
 * This class implements the complete vision-guided control loop:
 * 
 * 1. **Parse Command** → Natural language → AIActions
 * 2. **Take Screenshot** → Capture current GUI state
 * 3. **Analyze Vision** → Gemini analyzes screenshot
 * 4. **Execute Action** → Send gRPC command to GUI
 * 5. **Verify Success** → Compare before/after screenshots
 * 6. **Refine & Retry** → Adjust parameters if action failed
 * 7. **Repeat** → Until goal achieved or max iterations reached
 * 
 * Example usage:
 * ```cpp
 * AIGUIController controller(gemini_service, gui_client);
 * controller.Initialize(config);
 * 
 * auto result = controller.ExecuteCommand(
 *     "Place tile 0x42 at overworld position (5, 7)"
 * );
 * 
 * if (result->success) {
 *   std::cout << "Success! Took " << result->iterations_performed 
 *             << " iterations\n";
 * }
 * ```
