feat(gpu/assets): Fix tests, integrate bumpy 3D renderer and procedural assets

- Fixed test_sequence by restoring MainSequence::init_test for mocking.
- Corrected CMakeLists.txt dependencies and source groupings to prevent duplicate symbols.
- standardizing Effect constructor signature for seq_compiler compatibility.
- Implemented Hybrid3DEffect using bumpy Renderer3D and procedural NOISE_TEX.
- Updated MainSequence to support depth buffer for 3D elements.
- Formatted all source files with clang-format.
