Refined car physics constants and applied coordinate fixes to
Example Two. Implemented wheel rotation functionality for steering
and improved camera alignment logic. Updated documentation
and debugging task configurations.

Move visual components to child entities to prevent self-collision
with shape casters. Add a system to exclude the car from shape
cast hits and update the example.

- Update texture constants and UV scale values
- Adjust car heighting and ground-snapping logic

Separate visual and camera components to allow nested transforms.
Implement terrain height detection via raycasting and add
debugging gizmos.
