Detailed Description

Table model that caches node data from Graph and writes back via the Graph API.

Fixed columns: #, Label, Visible, Shape, Size, Color. Dynamic columns: one per custom attribute key reported by the graph.

Rebuilds the internal cache from graph.

Rebuilds the internal row cache from graph.

Calls beginResetModel() / endResetModel() so connected views repaint.

All vertices (enabled and disabled) are included; the Visible column reflects the vertex's enabled state. Custom attribute keys are taken from Graph::graphHasVertexCustomAttributes().
