ZeroGpuListener 0.1.2 API

```
public interface ZeroGpuListener

                    
```
Optional host-facing lifecycle callbacks (guardrail state changes). All methods have empty defaults so hosts implement only what they care about. Callbacks arrive on the SDK's IO dispatcher — hop to the main thread before touching UI.
