feat(gpu): Integrate bumpy 3D renderer into main demo

- Added depth buffer support to MainSequence.
- Implemented Hybrid3DEffect for the main timeline.
- Fixed effect initialization order in MainSequence.
- Ensured depth-stencil compatibility for all scene effects.
- Updated demo sequence with 3D elements and post-processing.
