Improve typing to mypy mostly-strict

[ducky64]

Mostly mechanical fixes to type annotations. A lot of adding -> None , or *args: Any.

Some code logic cleanup that does not affect output.

Two checks are currently ignored, which may be fixed in future PRs:

• explicit export (module-level __all__)
• default Any in Generics, allowing the usage of things like Port in type signatures

Pull request overview

This pull request improves type annotations throughout the codebase to achieve mypy mostly-strict compliance. The changes are largely mechanical, adding return type annotations (-> None) to methods and properly typing *args and **kwargs parameters.

Key Changes

• Migrated mypy configuration from mypy.ini to pyproject.toml with strict mode enabled
• Added -> None return type annotations to hundreds of methods
• Added Any type annotations to *args and **kwargs parameters
• Improved return type annotations for various methods
• Fixed type-related issues and removed unnecessary type: ignore comments
