Two-player decks shed LIFESAVER, as the card itself instructs

"Not applicable in a 2-player game." — the card face. New games deal
from deck revision 2, which removes it when exactly two wizards sit
down; three or more keep it. The revision travels in GameConfig and
the persisted start line, and stored games without one replay against
the original build — changing an existing game's deck composition
would scramble its deterministic replay. Test pins all three cases:
removed at two, present at three, present in legacy two-player games.
