🪀 Yo-Yo Physics Simulation — 2D Side View, Energy Split and Sleep Decay

2D companion of the yo-yo simulator: side view of the throw, sleep and climb cycle, translational versus rotational energy bars, height and speed traces, and a geometry-based moment-of-inertia ratio, using the same state machine as the 3D page.
