Faentum's Deep Sea Expansion

Fixed Spawning: Leviathans no longer overpopulate the oceans like fish; they are now rare, isolated encounters deep in the ocean depths ($Y < 45$).

Improved Hitboxes: Adjusted the bounding box so players can properly attack and hit the creature's entire body instead of just the head.

Optimized Behavior: Tweaked AI tasks so the Leviathan smoothly cruises through the water and tracks the player visually without freezing in place.
