feat: full engine scene — torus knot + 4 cubes + 3 spheres + floor + grid

Browse Source 
- 10 entities in ECS World with Transform + Mesh components
- Torus knot (center, scale 1.5) rotating around Y
- 4 cubes (left/right/front/back) rotating at different speeds
- 3 spheres (procedural, 32x16) rotating around X
- Floor (20x20 flat cube) + grid (ProceduralMesh.CreateGrid)
- Camera at (0, 3, -12) looking at (0, 0.5, 0)
- Mesh cache: buffers created lazily per entity ID on first frame
- Diffuse lighting on all objects
- 0 validation errors, ~2300 FPS
