Make quiescence-search mate proving sound. #201

Closed cosmobobak closed 1 month ago

200 made it possible for quiescence-search nodes to soundly detect checkmates. Unfortunately, there may still be mates being unsoundly propagated up the tree.

Update: This makes no sense. Quiescence search can always exit via stand-pat.
