fix(3d): Restore and enhance 3D shadows

- Elevated objects in test_3d_render to avoid shadow occlusion.
- Slanted light direction for more visible, elongated shadows.
- Sharpened shadows by increasing k constant to 32.
- Cleaned up debug printfs from previous turns.
- Maintained skip_idx logic for robust self-shadowing prevention.
