Joey Yakimowich-Payne b93b4b7322 feat(engine): mechanic effect primitives (absorb/reflect/range/block/promotion) T3 Wave 2 batch B. Implements 5 game-mechanic primitives that seed specs the engine's existing pipelines (T22 will wire) consume: - absorb-damage-with-attribute: seeds {AbsorbDamageAttr, AbsorbDamageRate}. - reflect-damage: seeds ReflectDamagePercent (0-100, validated). - modify-movement-range: composes with T1's range-bonus by reading existing RangeBonus (default 0) and writing existing+delta. - block-move-type: appends a move-type filter into BlockedMoveTypes. - override-promotion: writes the canonical PromotionOverride (mirrors T1's promotion-override descriptor exactly). ChessAttrMap gains AbsorbDamageAttr, AbsorbDamageRate, ReflectDamagePercent, and BlockedMoveTypes for the new fact namespaces. Engine integration deferred to T22; this batch is data-seeding only. All 5 register in PRIMITIVE_REGISTRY via side-effect import. Each primitive ships with ≥3 vitest scenarios.		2026-04-19 17:41:44 -06:00
