Modernize packaging, and update Python support

Summary:
- Switch to PEP 621 pyproject.toml with Hatch & VCS-based versioning (hatch-vcs)
- Remove legacy setup.py and setup.cfg
- Update supported Python versions to 3.9–3.13 in tox and CI
- Upgrade github actions

Refactor tox.ini:
- Remove python setup.py sdist from docs env
- Add flake8 as a dependency for pep8 env
- Clean up and document Sphinx build process
- Remove all references to unsupported Python versions (3.6–3.8)
- Ensure all test/lint/build workflows are modern and reproducible

Adding Changelog file that was previously auto-generated.
