`atTimes: ["??:05"]` runs a build five past every hour. The pattern expands
to its 24 concrete slots before the due-slot match, so each hour is its own
slot in the trigger state and fires once — the existing per-slot semantics
carry over unchanged, including that only the latest due slot of a day
triggers and that a slot whose pool is still building is retried until it
starts.
Only the hour may be a wildcard; anything else is skipped with a warning.
