Better Mob Combat Reimagined 1.1.12 - Villager / Custom Model Animation Fix

Main fix

• Fixed Villager Retaliation / Kingdom villagers animating their body while the visible weapon arms stayed frozen.
• Villager Retaliation uses a separate held-item combat model with independent RightArm / LeftArm parts and a separate crossed-arms branch. BMC now handles that model layout directly instead of assuming the normal villager arm tree.

EMF / Fresh Animations

• Fixed the whole-model EMF reapply path using the animator's raw authored arm set after BMC had already calculated a broader owned weapon-arm set.
• BMC now reapplies the synchronized logical weapon arm even when Player Animator introspection does not report that arm as authored.
• One-handed EMF attacks now respect the synchronized offhand flag and the mob's left-handed state.
• Two-handed attacks continue to own both arms.
• When a custom EMF model exposes a separate crossed-arms branch, BMC hides that branch only for the attack render and forces the actual weapon arms visible.

Non-EMF custom models

• Added temporary visibility ownership for generic humanoid/custom villager models.
• During a BMC attack, a separate arms / crossed_arms branch is hidden while the real leftArm / rightArm weapon branches are made visible.
• Parent arm containers are detected and are not hidden accidentally.
• All temporary visibility changes are restored at the end of the entity render.
