createPacketInteractionEntity

Creates a packet-only Interaction entity for click detection. This entity is invisible to players but receives their clicks. Should be called after the model is spawned. Props get a compact client-targetable interaction surface for entity-use input that Bukkit may not otherwise expose. Dynamic models deliberately stay on exact OBB air/block routing plus their backing-ID alias: a single axis-aligned square large enough to cover a long or rotated OBB would swallow unrelated clicks in its empty corners. A steerable mount is the exception: every click on it is meant to seat the rider. So is a dynamic model that asks for a click surface (setClickSurface). Either is sized from its hitbox bone, or from the model's own bounds when it has none.
