-- Cancel CI jobs that can never run (called by scripts/cancel_unrunnable.sh).
--
-- A job whose runs-on names a label no Windy Git runner offers (ubuntu-latest,
-- macos-latest, windows-latest …) waits forever: Gitea evaluates a job's `if:`
-- only when a runner picks it, so even `if: false` / tag-only jobs sit in the
-- queue, invisible to /actions/tasks, and keep their run "waiting" for good.
-- After 30 minutes they are cancelled here; the run's status is then recomputed
-- (failure > still-active > cancelled > success), the same precedence Gitea uses.
-- Keep RUNNER_LABELS in step with deploy/runner/config.yaml.
