Remove deleted Icarus's copy for good, so any misjudgment about which
file it was could not be undone. It now moves the copy to the Recycle
Bin through IFileOperation. A progress sink aborts any delete the shell
would do permanently (subst drives, no Recycle Bin, too big for it);
then Remove says so and leaves the file and its cache. The decode cache
is still deleted outright, since a decode rebuilds it.

A link in Valorant's folder back to Icarus's copy no longer counts as
Valorant still having the replay: the check no longer follows links,
the same as the listing.
