Add GdUnit4 testing framework with comprehensive test coverage

- Add GdUnit4 v6.2.1 framework in addons/gdUnit4/ - Create test directory structure (tests/unit/, tests/integration/, tests/mocks/) - Add unit tests for MusicPlayer.gd (8 tests) - Add unit tests for MainWindow.gd (15+ tests) - Add unit tests for Settings.gd (5 tests) - Add unit tests for Playlist.gd (11 tests) - Add integration tests for full flow (10+ tests) - Add MockHTTPRequest for HTTP request mocking - Add TestHelpers with utility functions - Add Gitea Actions CI workflow (.gitea/workflows/test.yml) - Add .runsettings for GdUnit4 CLI configuration - Add run_tests.sh for convenient test execution - Add TESTING.md with comprehensive documentation - Add TESTING_PLAN.md with implementation details - Update .gitignore for test artifacts - Enable GdUnit4 plugin in project.godot Features: - Test button functionality (play, pause, search, sync, etc.) - Mock REST API requests to server - Test complete application flows - Run tests in CI (headless mode) - Run tests in GUI for visual feedback - JUnit XML and HTML test reports Generated by OpenCode AI assistant.
