Same rule mash-playbook has been running in production: role bumps from
mother-of-all-self-hosting merge via branch push (no PR) once the branch's
CI checks pass. The trust basis is the role repositories' own gates - each
release is cut by Molecule-verified, autotagged merges over there.

Bumps of devture roles and everything else keep their PRs. Extending the
same treatment to devture roles (here and in mash-playbook) is a discussed
follow-up.
