Battle Buddy

• Added textures for the BattleBuddy to give it a more polished and unique look. • Introduced a fun new feature where the BattleBuddy will fish while idle when it has a fishing rod. • Added door-opening support, allowing BattleBuddies to intelligently open doors while navigating. • This includes support for iron doors(still working on them closing after opening). • Cleaned up code and reorganized logic to better support future visual and AI features.
