Module store 

Headless runtime store (B-layer) for node graphs.

This is the ergonomic “single entry point” that B-layer consumers want:

• authoritative Graph (serializable document),
• per-user/per-project NodeGraphViewState (pan/zoom/selection),
• undo/redo history (GraphHistory),
• dispatch methods that return a full-fidelity NodeGraphPatch.
