Keep the deadline-guard check name branch protection matches

The guard was widened to cover Time::getMillis() and unqualified getMillis(),
and renamed to suit. Upstream branch protection matches required checks by name,
so a rename means the old name never reports and merges block on a check that
will never arrive.

Widen the guard, keep the name; the descriptive text carries the broader scope.
