DoxHitbox

MultiHitboxLib is no longer used at all.

That mod has been discontinued, and this one only ever used it to walk from a

part entity back to its parent — which Forge's own PartEntity already provides.

MHLib's parts extend that class, so setups that still have it keep working

exactly as before. One less dependency, wider compatibility.

Fixed: part scale is now carried in the pose snapshot. Entities whose model parts

are scaled up or down had hitboxes that no longer matched what you see.

Added: per-entity render scale can be registered from code instead of hand-tuning

`scales` in hitbox_obb.json. (Leave `scales` empty — it overrides the automatic value.)

Fixed: a client-side memory leak during long sessions. Model parts accumulated in

the part-name registry; they are now weakly held and collected normally.
