ci: run the release through the shared python-release reusable

Replaces four hand-rolled jobs (10 step-level third-party actions) with one
caller job and zero stray uses. Build, twine check, GitHub Release and the
PyPI upload all move into netresearch/.github, so the pinned action versions
stay maintained centrally.

Nothing working is lost, because the publish path never worked: the repo has
no Actions secrets at all, so PYPI_API_TOKEN and TEST_PYPI_API_TOKEN resolved
to empty in every run, and there are no tags, no releases, and no cli-audit
package registered on PyPI. Rather than carry a job that is guaranteed to
fail, publishing is switched off and the two prerequisites are documented in
the workflow: a PyPI Trusted Publisher for this repo, and the GitHub
Environment it names (only `copilot` exists today). Flipping publish-pypi to
true is then the whole change — the reusable uploads via OIDC, so no token is
needed at all.

Two behaviours the reusable could not express until now were added to it
first (netresearch/.github#292), so they survive the migration:
- release-files: attaches the sdist and wheel, as softprops/action-gh-release
  did via `files: dist/*`.
- prerelease: auto — reproduces the previous
  contains(alpha|beta|rc) expression and additionally covers the PEP 440
  spellings it missed. At 2.0.0-alpha.6 this is the normal case here.

Dropped deliberately as local quirks: the CHANGELOG-derived release body
(replaced by --generate-notes) and the separate TestPyPI dispatch path.
