- Transform pyproject.toml from Poetry format to PEP 621/735 - Use hatchling as build backend instead of poetry-core - Add dependency-groups for dev dependencies (PEP 735) - Convert Python-conditional dependencies to PEP 508 markers - Add uv.lock and remove poetry.lock - Update noxfile.py to use uv as venv backend - Update .pre-commit-config.yaml: poetry run → uv run - Update Makefile: poetry run → uv run, shell-based version bumping - Update CI workflows to use astral-sh/setup-uv@v4 - Update CLAUDE.md with uv commands - Add .python-version file (3.10) - Remove constraints.txt (no longer needed with uv) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Pin black==24.4.2 and isort==5.13.2 to match poetry.lock versions - Add [tool.black] with target-version=[] to prevent auto-inference from requires-python (which would change formatting behavior) - Revert .python-version to 3.10 (matches noxfile python_dflt) Black 24.x auto-infers target_version from [project].requires-python in PEP 621 format, but Poetry's [tool.poetry.dependencies].python wasn't read by black. Setting target-version=[] maintains the pre- migration formatting behavior. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Pull request overview
This PR migrates the project's package management from Poetry to uv, modernizing the dependency management tooling and aligning with PEP standards. The migration includes converting pyproject.toml to use PEP 621 project metadata and PEP 735 dependency groups, switching from poetry-core to hatchling as the build backend, and updating all CI/CD workflows and developer tooling to use uv.
Changes:
- Converted
pyproject.tomlfrom Poetry format to PEP 621/735 standards with hatchling build backend - Updated CI workflows (GitHub Actions) to use
astral-sh/setup-uv@v4instead of Poetry installation - Modified developer tooling (noxfile, Makefile, pre-commit hooks) to use
uv runinstead ofpoetry run
