feat: add OpenGL abstraction layer with RAII resources

- Replace window class with cbt::opengl::context - Add buffer resource (VBO, EBO, UBO, SSBO) with move semantics - Add texture resource with format/type enums and filtering - Add descriptor_set for Vulkan-style resource binding - All resources use RAII with proper cleanup
