Publish free-threaded Windows ZIP artifacts

Recognize the Windows free-threaded t version marker when listing release
files.

Give each free-threaded Windows embeddable ZIP architecture-distinct metadata
so generated slugs do not collide and the files stay non-download-button
artifacts. Add pytest coverage for prerelease and final release metadata
generation.
