Update project files and enhance rendering system

Browse Source 
Added:
- Updated `.gitignore` to ignore the `[Bb]uild/` directory.
- Additional tasks added to the roadmap in `README.md` for light unit standardization and GPU backend support.

Changed:
- Removed line in `settings.json` that disabled error squiggles for C/C++ code.
- Modified `Triangle.h` to include `material_id` in `triangle_t` and reorganized properties.
- Reordered parameters in `triangle_collection_init` for clarity.
- Updated `shading_context_t` in `Material.h` and added size parameter to `material_create`.
- Streamlined initialization in `scene_init` and updated `scene_free` for proper resource management.
- Updated `window_create` in `Window.h` to accept a `render_job_t` parameter.
- Introduced `renderer_start` in `Renderer.c` to handle rendering jobs and optimized pixel rendering logic.
