Towards parity with Mesa's core repo practices

[rht]

This issue should be informative: projectmesa/mesa-examples#11.
And a continually updated list (so that future Mesa projects can get to parity quickly):

• Use declarative pyproject.toml instead of setup.py
• Setup Ruff, codespell, Black checks: https://github.com/projectmesa/mesa/blob/main/.pre-commit-config.yaml (must be via pre-commit instead of GitHub Actions, because the former is much faster)
• Setup CI for testing
