Module physics 

Physics engine for entity movement with vanilla Minecraft parity.

This module implements the core physics simulation for moving entities through the world with proper collision detection, including:

• Step-up mechanics (climbing blocks ≤ max_up_step height)
• Sneak-edge prevention (staying on block edges while crouching)
• VoxelShape-based collision using AABB lists

The implementation closely follows vanilla’s Entity.move() method to ensure 1:1 movement validation for anti-cheat purposes.
