- Added conditional compilation for the ImGui Test Engine in `EditorIntegrationTest`, allowing for test registration and engine initialization when enabled.
- Updated the constructor and destructor to manage the test engine context appropriately.
- Improved the `Initialize` method to include test engine setup and registration, enhancing the integration testing capabilities.
- Ensured compatibility with scenarios where the ImGui Test Engine is disabled by providing default implementations for related methods.
- Commented out a large number of unused variable declarations and code segments in the `SaveSongs` function to improve readability and maintainability.
- This change does not affect the functionality but prepares the code for future enhancements by reducing clutter.
- Introduced new E2E test suite for comprehensive ROM testing, validating the complete ROM editing workflow.
- Added ZSCustomOverworld test suite to validate version upgrades and data integrity.
- Updated `EditorManager` to register the new test suites.
- Enhanced CMake configuration to include the new test files.
- Updated README to reflect the new testing capabilities and best practices for AI agent testing.
