Detailed Description

Central singleton that owns and coordinates all engine subsystems.

Startup sequence (see main.cpp)

Engine &engine = Engine::GetInstance();
engine.SetApplication(new Game());   // hand over ownership
engine.Init(1280, 720);              // GLFW → window → GLEW → app->Init()
engine.Run();                        // main loop until close requested
engine.Destroy();                    // app->Destroy() → GLFW cleanup

Main loop (Engine::Run)

Each iteration:

1. glfwPollEvents() → GLFW callbacks update InputManager.
2. Compute deltaTime with a steady_clock timestamp.
3. app->Update(dt) — game logic runs here.
4. Collect CameraData and LightData from the active Scene.
5. RenderQueue::Draw() drains all submitted RenderCommands.
6. glfwSwapBuffers() — present frame.

Note

Engine is a non-copyable, non-movable singleton (Meyer's singleton pattern). Access it anywhere via Engine::GetInstance().
