feat: FreeFlyCameraController — interactive WASD + mouse look

Browse Source 
- Program.cs: create Camera entity in ECS World, FreeFlyCameraController
  with WASD movement, Q/E up/down, Shift boost, right-click mouse look
- VulkanRenderer.RenderWorld: queries Camera from World, computes VP
  from Camera.GetViewMatrix() * GetProjectionMatrix()
- Camera aspect ratio auto-updated on window resize
- Fallback to hardcoded VP if no Camera entity found
- Torus knot still rotating via push constant model matrix
- 0 validation errors
