New format: WOC (Wowee Open Collision) — binary collision mesh for custom zone walkability. Magic WOC1 (0x31434F57). - WoweeCollisionBuilder::fromTerrain() generates collision triangles from terrain heightmap with slope classification (50 deg threshold) - Per-triangle flags: walkable (0x01), water (0x02), steep (0x04) - Respects terrain holes (skips triangles in hole regions) - Binary save/load with bounds, tile coords, triangle data - Auto-exported on zone save alongside WOT/WHM/WOM/WOB - Added to content pack validation (score now 0-7) - FORMAT_SPEC.md v1.1 updated with WOC binary layout - 19 new test assertions: flat terrain generation (32k tris all walkable), save/load round-trip, hole skipping - 328 total assertions across 84 test cases
