Subject: [PATCH] Add GitHub Actions workflow for PyPI publishing on tag
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Uses PyPI trusted publishing (no API tokens needed).
Triggers on version tags (v*.*.*). setuptools_scm derives
the version from the git tag automatically.

After merging, configure trusted publishing on pypi.org:
  Project: cryptoadvance.spectrum
  → Publishing → Add a new publisher
  → Owner: cryptoadvance, Repo: spectrum
  → Workflow: pypi-publish.yml, Environment: (blank)
