Punchy! - First person animations

FEATURES
- We now render detailed 3D vanilla item models in hand instead of the default Minecraft textures (For now, not all of them).
- Fully animated 3D models in hand with physics for all BOATS, RAFTS, CHESTS, and MINECARTS.
- Improved walk on water behavior.
- When leaving the water, the player shakes their arms and spawns water particles, giving clear feedback that the character is drying off.
- Complete rewrite of the state machine for multiple items that required exclusive behaviors.
- Cleaner and more organized codebase, allowing faster updates and releases.
- Added two-handed spear support.
- Reworked swords now play sequence attack not random anymore.

FIXES
- Fixed multiple bugs that caused animations to stop working or get stuck on the last frame.
- Fixed lantern physics.
- Improved overall animation flow and smoothness.
