feat(D-01/A): poseType, helpers, OWNERSHIP ComponentType (A4, A5, A6)

- DataDrivenItemDefinition: add poseType field, parsed from JSON "pose_type"
- PoseTypeHelper: resolves PoseType from V2 definition or V1 ItemBind fallback
- BindModeHelper: static bind mode NBT utilities (isBindItem, hasArmsBound,
  hasLegsBound, cycleBindModeId) — works for V1 and V2 items
- CollarHelper: complete static utility class for collar operations with
  dual-path V2/V1 dispatch (ownership, features, shock, GPS, choke, alert)
- ComponentType: add OWNERSHIP enum value
- OwnershipComponent: stub class (lifecycle hooks added in next commit)
