- Add glm dependency for matrix transformations - Replace triangle with 6-face colored cube - Add MVP shader uniforms (model, view, projection) - Enable depth testing for proper 3D rendering - Spin cube around (1, 0.5, 0.3) axis style: fix trailing return type for move assignment operators - buffer/texture/shader/vao: use auto fn() -> T& style - Document trailing return type convention in AGENTS.md
