Anti-Smooth

Changes

• Velocity no longer gets applied to leashed mobs in 1.21.6+
  • This is due to mobs falling down and rubber banding whenever they are meant to be stationary
  • Resolves #2, though admittedly the solution isn't very glamorous
• Added minecarts to the default list of unaffected entities

Fixes

• Fixed mobs clipping through walls by shrinking their hitboxes client-side during solid collision detection (Resolves #1)
