Pull Request Overview

This pull request separates typing and style checks into dedicated GitHub Actions workflows, moving them out of the main unit test workflow to improve CI organization and performance.

• Removes code formatting and MyPy checks from the unit test workflow
• Creates a new dedicated typing checks workflow that runs MyPy on multiple Python versions
• Replaces the automatic code formatting workflow with a code style checks workflow that validates formatting without auto-fixing
