MCL 2.1.0.1 downloads its seven catalog JSONs again whenever it returns to
its start screen, seconds after writing the finish tag, so every finished
cache failed the newer-than-tag check. Check only the files a run writes for
its selection (OperatingSystem.json, HardwareDriver.json, LanguagePacks.json).
packages.json now lists the KB5043080 checkpoint CU for 24H2, but MCL never
downloads it; say so instead of counting it in the plan.
