Basic 3D Scene (Capsule) - Bullet Physics

The same first scene as E01_3D_BasicScene, running on the legacy Bullet physics engine instead of Bepu. The scene code is character-for-character identical; the only difference is which toolkit package is referenced and which namespace is opened. That is the point of the example - physics is swapped at the project level, not by rewriting the scene.

The Program.cs file shows how to:

Running the base 3D scene on the legacy Bullet physics engine
Switching engine by namespace: Stride.CommunityToolkit.Bullet in place of .Bepu
Why the scene code needs no change when the physics engine does
Using helpers: SceneSetup3D, UseSkybox, CreatePrimitive
