Hatch environments were replaced with tox to align with the rest of the tox-dev ecosystem tooling. This also moves from mypy to ty for type checking and from optional-dependencies to PEP 735 dependency-groups. CI workflows now install tox+tox-uv instead of hatch, ReadTheDocs builds use tox for docs generation, and pre-commit gains tox-toml-fmt.

The platformdirs project was the last tox-dev project still using hatch for environment management. 🔧 Migrating to tox aligns it with the rest of the ecosystem (filelock, tox, etc.) and brings consistency to how all tox-dev projects are developed and tested.
This replaces hatch environments with a
tox.tomlconfiguration covering test, fix, coverage, type checking, docs, package metadata validation, and dev environments. Theoptional-dependenciessections move to PEP 735dependency-groups, andmypyis replaced bytyfor type checking. CI workflows now installtox+tox-uvinstead ofhatch, ReadTheDocs builds docs through tox, andtox-toml-fmtis added to pre-commit.Coverage path mappings are updated for tox's
.tox/layout. The release workflow bumps to Python 3.14. All existing functionality (multi-version testing, coverage aggregation, docs, linting) is preserved under the new runner.
