This pull request introduces several improvements to Vue reactivity and user experience in the graph node and widget system. The main focus is on ensuring that changes to node and widget data reliably trigger updates in Vue components, improving drag-and-drop support for nodes, and enhancing widget value handling for better compatibility and reactivity. **Vue Reactivity Improvements:** * In `useGraphNodeManager.ts`, node data updates now create a completely new object and add a timestamp (`_updateTs`) to force Vue's reactivity system to detect changes. Additionally, node data is re-set on the next tick to guarantee component updates.

Watches are updated to use this getter for more reliable reactivity.

Node callbacks (`onDragOver`, `onDragDrop`) are used for custom validation and handling.

There is also a commented-out call to mark the canvas as dirty for potential future refresh logic.
