 * @file TestAIEditorGUI.cpp
 * @brief Integration tests for AIEditorGUI (Phase 1.3)
 * @author Olympe Engine
 * @date 2026-02-18
 * 
 * @details
 * Tests all components of AIEditorGUI:
 * - Initialization and shutdown
 * - Graph creation and management
 * - Node creation via palette
 * - Undo/redo functionality
 * - Validation integration
 * - Save/load roundtrip
 * - Multi-graph tabs
 * - Panel integration
 * 
 * @note This is a test file. Test output uses std::cout which is acceptable
 * for test reporting purposes. Production code uses SYSTEM_LOG.
