Remove Poetry files and complete uv migration

Summary

Cleans up all remaining Poetry-related files and configuration after the uv migration in PR #3. The project now uses uv exclusively as its package manager.

Deleted files:

• poetry.lock, poetry.toml — replaced by uv.lock (already committed)
• .github/actions/setup-poetry-env/action.yml — unused composite action
• requirements_ci.txt — only contained ycyc, used by old make check integration tests
• tox.ini — referenced Poetry and outdated Python versions (3.8–3.11)

Modified files:

• pyproject.toml — removed [tool.poetry], [tool.poetry.dependencies], [tool.poetry.dev-dependencies] sections
• .github/workflows/main.yml — removed Poetry installation steps, CI now runs make test only
• Makefile — check target now runs pre-commit run -a instead of versifier integration commands; publish target uses uv publish instead of poetry publish

Review & Testing Checklist for Human

• make check no longer runs versifier integration tests — the old check target ran versifier requirements-to-poetry, extract-private-packages, and poetry-to-requirements as integration tests against this repo. These are now replaced with pre-commit run -a. Verify you're okay losing this integration coverage (unit tests still cover 117 tests at 98% coverage)
• CI only runs make test, not make check — pre-commit hooks are no longer exercised in CI. Consider whether make test check should be restored in CI
• publish target lost dry-run step — previously did poetry publish --dry-run before actual publish. Now directly runs uv publish. Confirm this is acceptable for your release workflow
• [tool.poetry] removal — versifier/poetry.py reads poetry.lock and calls Poetry CLI internally. Running versifier's own CLI commands (e.g. versifier extract-private-packages) on this repo itself will no longer work since poetry.lock and [tool.poetry] are gone. This only affects using versifier on its own repo, not on other target repos

Notes

• The [tool.versifier] config section is preserved (still references private_packages, poetry_extras, etc.)
• uv.lock was already committed in the previous PR and is unaffected by this change

Pull request overview

This PR finishes the repository’s migration from Poetry to uv by removing remaining Poetry-related files/config and simplifying local/CI workflows to rely on uv.

Changes:

• Deleted Poetry and tox artifacts (poetry.lock, poetry.toml, tox.ini) plus now-unused CI requirements/action files.
• Removed [tool.poetry*] sections from pyproject.toml, leaving the project on PEP 621 metadata + uv lockfile usage.
• Updated Makefile and GitHub Actions workflow to stop installing/using Poetry and to run tests via uv.

make check now runs uv run pre-commit ..., but pre-commit is not listed in pyproject.toml dependency groups and does not appear in uv.lock, so this target will likely fail in a fresh environment. Add pre-commit to the appropriate dependency group (and update uv.lock), or switch the Makefile to use a uv tool/uvx invocation so the tool is always available.

Fixed both issues:

1. Added pre-commit>=3.0.0 to [dependency-groups] dev in pyproject.toml and updated uv.lock
2. Updated CONTRIBUTING.md to reflect the uv + make install/check/test workflow (removed Poetry/tox references)

CI passes on all 3 Python versions.

The publish target no longer uses PYPI_TOKEN (previously wired into Poetry) and now just runs uv publish, which will break existing workflows that relied on make publish picking up PYPI_TOKEN. Consider either mapping PYPI_TOKEN to whatever authentication mechanism uv publish expects (env var or config file), or adding an explicit check/error message when credentials are missing; also consider restoring an equivalent preflight/dry-run step if your release process depended on it.

[Copilot]

After removing Poetry/tox support, contributor guidance is now stale: CONTRIBUTING.md still instructs using poetry install/shell/run and running tox. Consider updating the contributing docs to reflect the uv + make install/check/test workflow so new contributors aren’t blocked.
