Carried villagers' head and body jitter on Fabric 26.2 #996

Environment

• Minecraft 26.2
• Fabric
• Carry On 2.11.0 (carryon-fabric-26.2-2.11.0.jar)

Steps to reproduce

1. Pick up a villager with Carry On.
2. Keep carrying it and watch its head and body, especially while moving or turning.
3. The head/body often keep shaking or changing orientation between frames. Villagers with professions are affected too.

Expected behavior

The carried villager keeps a stable rendered orientation.

Suspected cause

CarriedObjectRender resets xRotO and yRotO before extractEntity(entity, partialTicks), and CarryRenderHelper.applyEntityTransformations resets them again. The current xRot and yRot can still contain the entity's original NBT rotation. Each frame then interpolates from zero toward that old angle. The living-entity head/body rotations also use interpolated state.

Resetting current X/Y rotations together with their previous values in both paths resolves the mismatch and covers other carried LivingEntity types.
