The operator wants a reviewed pull request merged without a session calling
the merge tool again after every recheck. The reviewer marks it ready (label
mesh/ready and a comment "ready at <full head sha>"); the forge's open-pulls
read carries the mark, and mesh-delivery merges through gitea_merge_pull_request
at that head, in a group's order once its composed check passed. A push after
the mark clears it; a failed check is said on the pull request and as a
stalled line.
