Add E2E and ZSCustomOverworld test suites for comprehensive testing

- 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.
