Claude Bot 000aad362a feature: implement cut and paste functionality (closes #8) ...

- Add CutStore (Zustand) to store cut node IDs, node data, edges, and source graph ID
- Update graphToDot() to render cut nodes with dashed grey style for visual indication
- Add 'Cut' action to node context menu; 'Paste' action to empty-area context menu
- Cut logic: captures selected nodes (or right-clicked node if none selected) plus
  all nodes reachable by outgoing edges from those nodes; clears selection afterwards
- Paste logic: adds cut nodes/edges to target graph, removes them from source graph
  in GraphsStore; pasting on the same graph as the cut source cancels the cut
- Graph re-renders automatically when cutNodeIds changes via useCutStore subscription
- Clear cut store on file load for consistency
- Add E2E tests covering: Cut menu visibility, Paste menu visibility, cut styling,
  linked-node inclusion, cross-subgraph paste, source-graph cleanup, same-graph cancel
