Reviewer's Guide by Sourcery

This pull request updates the codebase to officially support Python 3.13 and drops support for Python 3.8. The main changes involve updating type annotations, particularly replacing List with list, Dict with dict, and Type with type. These changes align with Python's type hinting syntax improvements in more recent versions.
