sladro 6fd84e4ca3 fix: correct ray-AABB intersection algorithm to handle rays starting inside AABB ...

- Fixed intersection distance calculation to handle three cases:
  - Ray starts outside AABB: use entry point (tMin)
  - Ray starts inside AABB: use exit point (tMax)
  - AABB behind ray: skip intersection
- This fixes the issue where no intersections were detected (intersections=0)
