_⚠️ Potential issue_ | _🟠 Major_

**Add required type hints and Google-style docstrings to public test methods.**

All public test methods here should include parameter/return type hints and Google-style docstrings with Args, Returns, Cost, and Example sections. Please apply across the file.

As per coding guidelines: “All public methods in generator classes and test files must include type hints for parameters and return values”, “All public methods should include docstrings with Args, Returns, Cost information, and Example sections”, and “Write docstrings for every function using Google style format”.

In `@tests/test_xdg_paths.py` around lines 21 - 130, The test file lacks required
type hints and Google-style docstrings on public test methods; update each
public test method (e.g., TestAppName.test_app_name_is_video_ai_studio,
TestConfigDir.test_uses_xdg_config_home,
TestConfigDir.test_xdg_takes_priority_over_platform_default,
TestConfigDir.test_unix_fallback, TestConfigDir.test_windows_uses_appdata,
TestCacheDir.test_uses_xdg_cache_home, TestCacheDir.test_unix_fallback,
TestCacheDir.test_windows_uses_localappdata,
TestStateDir.test_uses_xdg_state_home, TestStateDir.test_unix_fallback,
TestStateDir.test_windows_uses_localappdata,
TestDefaultConfigPath.test_is_yaml_file,
TestDefaultConfigPath.test_is_inside_config_dir,
TestEnsureDir.test_creates_directory,
TestEnsureDir.test_existing_directory_no_error,
TestEnsureDir.test_returns_same_path) to include explicit parameter and return
type hints (e.g., tmp_path: Path -> None) and add a Google-style docstring for
each with Args, Returns, Cost, and Example sections describing inputs/outputs
and behavior; keep semantics unchanged and only add annotations and docstrings
to public methods.
