feat: Add seamless bump mapping with procedural noise

- Replaced white noise with smooth value-like noise.
- Implemented periodic texture generation (seam blending).
- Integrated bump mapping into Renderer3D using finite difference of displaced SDF.
- Updated test_3d_render with noise texture and multiple SDF shapes (Box, Sphere, Torus).
