Faentum's Deep Sea Expansion

The Leviathan Awakens: Changed behavioral characteristics from Passive to Aggressive (Mob). It will now actively hunt players!

Boss Status: Added a dedicated boss health bar (Purple), unique tracking mechanics, and a custom entity label.

Massive Stat Buff: Max Health increased to 500 HP, Melee Attack Damage set to 14, and defeating it now rewards a massive pool of 1,000 XP.

Combat Overhaul: Added Attack Knockback, allowing the Leviathan to launch players backwards upon striking. Added 100% Knockback Resistance to the Leviathan, making it immune to weapon recoil and completely unstoppable.

System Fixes: Completely rebuilt the core workspace codebase to fix major Java class compilation errors.
