"""The per-repo opt-out from the CI workflow (`.dep-freshness-no-workflow`).

A repo that runs the gate only locally (teatr-pw: no GitHub Actions minutes)
deletes `.github/workflows/dependency-freshness.yml` on purpose. Without an
opt-out the next fleet sweep puts it back, so the marker must stop the
installer from creating OR rewriting it -- and must not stop anything else.
