ci: migrate from Cirrus to GitHub Actions (#76)

* chore(ci): register slow marker and add py311/py312 tox envs

Pre-flight hygiene for the CI migration off Cirrus. Two provider-independent
fixes that de-risk the upcoming matrix:

- Register the slow pytest marker in setup.cfg so CI logs no longer carry a
  PytestUnknownMarkWarning on every run. The slow tests already exist
  (KirmansAnts stationary KS, two common tests); only the registration was
  missing.
- Add explicit py311 and py312 tox envs mirroring the existing py313 env.
  Without these, tox -e py311 falls through to the base [testenv] and runs
  the full slow suite, which would surprise the matrix CI.

* ci: migrate from Cirrus to GitHub Actions

Cirrus-CI shuts down 2026-05-31. Replace it with a 2-OS x 3-Python matrix
on GitHub Actions, restoring the wheel-install pattern and rewiring the
README badges. No-op for local development.

Workflow shape:
- build job (ubuntu-latest, Python 3.13) runs 'tox -e clean,build' and
  uploads dist/* as an artifact, so every matrix leg installs the SAME
  wheel and catches packaging bugs that per-job rebuilds miss.
- test matrix (ubuntu-latest, windows-latest) x (3.11, 3.12, 3.13) with
  fail-fast: false to mirror Cirrus' independent-task semantics.
- actions/checkout uses fetch-depth: 0 because setuptools_scm is
  configured with version_scheme = 'no-guess-dev' and refuses to build
  on shallow clones without tag history.
- actions/setup-python@v5 caches pip keyed on pyproject.toml + uv.lock.
  The torch CPU wheel is ~200 MB; the cache is the single biggest perf
  win across the matrix.
- Windows enables long-path support via PowerShell before any install,
  porting the Cirrus registry tweak.
- Coverage uploads per-leg with coverallsapp/github-action@v2
  parallel: true; a final coverage-finish job calls parallel-finished
  so Coveralls merges the six legs into one report.
- schedule cron at 04:00 UTC nightly runs the FULL suite (slow + fast)
  on master... (continued)
