check / check (push) Canceled after 0s
The canonical `.gitea/workflows/check.yml` gains a `concurrency` block grouped by workflow and branch with `cancel-in-progress: true`, so a new push cancels the older run on the same branch and no other, and its checkout step sets `persist-credentials: false`, so the job's token is not left in `.git/config`; `script/cibuild` needs none. Both come from `dnswatcher`, where a byte-identical re-vendor would have removed them. The workflow bullet of `prompts/REPO_POLICIES.md` and both checklists now describe the file as it is.
