feat: WGSL Uniform Buffer Validation & Consolidation (Task #75)

- Added  to validate WGSL/C++ struct alignment.
- Integrated validation into .
- Standardized uniform usage in , , , .
- Renamed generic  to specific names in WGSL and C++ to avoid collisions.
- Added  and updated .
- handoff(Gemini): Completed Task #75.
