Implement engine core: board assembly, movement, turns, combat, victory
Pure deterministic game core in @wizwar/engine: seeded RNG (mulberry32, state in GameState so seed+commands replays identically), sector assembly with rotation, junction merging, and wraparound warps (configurable pairings; the 2p diagram crosses its side openings), movement (3 + one number card), geometric line of sight, deck building from the verified card data (asserts 125/200 totals), and the command-to-event reducer: setup with TRAP! redraw and die-roll first player, punching (no combat round 1, no self-attack, once per turn), damage/death with killer-takes-cards and forced discard, treasure stealing with both victory conditions, pick-up-ends-turn, and end-of-turn draw. Events carry full spatial detail for future replay rendering; private card knowledge rides on visibleTo events with a redaction helper. 21 tests passing.
