Replace trivially-true Pp>=0 with concrete post-Setup pins (LeaderLife=20,
Pp=0, HandCount=3). Drop the unused seed parameter from SampleDeck - every
call already returned the same vanilla deck, and the StressN test name 'Random
Decks' overpromised. The cross-contamination property the test pins (parallel
LeaderLife[] equals sequential LeaderLife[]) holds with identical decks +
distinct masterSeeds, which is what's actually being verified.
