release.yml stopped running with the GitHub account, and nothing replaced
it: no tag has been cut since, so the publish job had nothing to build.
This ports its decision unchanged -- release only when main has commits
since the newest published release, and only if the tag does not already
exist -- to a job run by a Monday 09:17 UTC pipeline schedule. The schedule
lives on the project and sets RELEASE_WEEKLY=1; DRY_RUN=1 stops after the
decision.
The release, and so the tag, is created with a project access token rather
than the job token. That makes the tag an ordinary push, which starts the
tag pipeline and its publish job, replacing release.yml's direct call of
publish.yml. The checks are skipped in the release pipeline, as they were
on GitHub: main has already passed them.
