Replace mypy with ty (Astral)

Is your feature request related to a problem?

Currently, the project uses mypy for static type checking. While powerful, mypy can be slow, has complex configurations, and sometimes lacks ergonomics when working with modern Python features. This affects developer experience and feedback speed.

Describe the solution you'd like

Replace mypy with ty from Astral.
ty is a modern, fast type checker designed to be more user-friendly and performant. It provides faster feedback loops and simpler configuration, improving the developer experience.

Describe alternatives you've considered

• Keeping mypy as is and continuing to maintain its configuration.
• Using other type checkers like pyright or pyre.
