✅ Expected Behavior

When an entity is resting exactly on top of a partial-height block (e.g. slab at Y = 0.5), and has zero vertical velocity, the swept AABB test should not detect a collision, and allow free motion along X and Z axis.
In other words, an entity sliding across the top surface of a slab should not be blocked.

❌ Actual Behavior

In cases where the entity sits exactly at the boundary of the slab (Y = 0.5), and vertical velocity is zero, the swept AABB test reports a collision and the entity yeets off to fucking wherever.
