Joey Yakimowich-Payne 08b5f794a7 feat(chess): allow pawns-move-backward and double-pawn-sprint simultaneously Audited all 15 preset incompatibilities. Five of the six declared pairs are genuine mechanical conflicts (rook-warp vs wrap-board have contradictory board-topology semantics; piece-hp vs explosive-rook define capture as damage vs removal; capture-to-win vs last-piece-standing are competing win conditions). The pawns-move-backward vs double-pawn-sprint pair is not — both are pure additive getExtraMoves hooks over the base pawn rule; the move sets are disjoint (backward-1 vs forward-2); and no generated move contradicts any other. Dropped the declaration from both preset files. Moved the mutually-incompatible-pair tests to use rook-warp vs wrap-board, which is the canonical genuine-conflict pair and exercises the same compat machinery.		2026-04-17 14:34:18 -06:00
