Detailed Description

Per-frame command list that batches and issues all draw calls.

Why a command queue?

Separating "what to draw" from "when to draw" gives the engine a clean boundary between game logic and rendering. Application::Update() submits RenderCommands by value; the engine drains and draws the queue once per frame after Update() returns.

Frame lifecycle

1. Game code (via MeshComponent::Update or manual calls) calls Submit().
2. Engine::Run() calls RenderQueue::Draw() after all updates are done.
3. Draw() iterates the command list, binds each material + mesh, uploads MVP and light uniforms, and issues the GL draw call.
4. The command list is cleared automatically at the end of Draw(), ready for the next frame.
