🔧 fix(type): resolve ty 0.0.25 type errors

[gaborbernat]

ty 0.0.25 introduced stricter type checking. This PR fixes the actual type errors and removes the temporary version pin.

Changes:

• Add _site_data_dirs, _site_config_dirs, _site_applications_dirs as concrete properties on PlatformDirsABC so XDGMixin.super() calls resolve
• Replace direct ctypes.WinDLL assignment with mocker.patch.object in tests
• Remove # type: ignore[misc] comments from _xdg.py
• Remove ty<0.0.25 version pin

You're basically the lead maintainer here so it's all up to you but have you considered pyrefly? When we introduce a type checking command in Hatch we will very likely use that over ty by default because its behavior is generally safer for users (example).

[gaborbernat]

Yeah, for now I prefer ty 🤔 but can change if OpenAI starts doing crazy things 😆

[ofek]

Fair enough! What do you prefer about its behavior?

https://pyrefly.org/blog/container-inference-comparison/ I don't really run into this because I consider it best practice to type annotate upfront such elements. It's more unified with the ruff/uv we already use, and is just as fast as pyrefly, and I already use it in all my other projects, so makes sense to not migrate everything else too now to pyrefly. (until few days ago I trusted Astral more than FB, but alas while I still trust Astral, OpenAI I'm not that eager so that benefit is gone).
