Pull request overview

This PR implements the foundational components for Sprint 01 of the LMGL graphics engine, establishing core rendering infrastructure, scene graph management, and comprehensive test coverage.

Key Changes:

• Complete implementation of the rendering pipeline (shaders, buffers, textures, framebuffers, vertex arrays)
• Scene graph system with hierarchical node transforms and mesh management
• Camera system with perspective/orthographic projection and screen-to-world unprojection
• Comprehensive test suite across all components with CI/CD improvements
