Set up, modernize, or update Python projects using the simple-modern-uv template: uv, ruff, BasedPyright, pytest, GitHub Actions CI, and tag-driven PyPI publishing. Use when starting a new Python project or package; when modernizing, upgrading, or migrating an existing Python package to uv (from Poetry, setuptools, pip, requirements.txt, or PDM); or when updating a project already built from simple-modern-uv to the latest template.
