CG-0MM3B510O0P25F1S: Migrate The Mind to shared setup helpers

Replace TheMindSetupOptions interface with MultiplayerSetupOptions type
alias and use resolveSetupOptions() with hardcoded playerCount: 2. Update
test to expect shared default names ('Player 1', 'Player 2') instead of
game-specific defaults ('Player', 'AI'). All 308 The Mind tests pass.
