Replace the custom toDebugGraph() method that generated JSON directly in C++ with a generic GDB Python script (debug_graph.py). The script traverses pointers and structures to build a graph representation for the VS Code Debug Visualizer, enabling external pointer display and more extensible visualization.
Update launch configurations to load the script and to disable array/string truncation (needed for the visualizer JSON). Add a debugAdapterConfigurations entry in settings.json to use the expression template $debug_graph(${expr}) for the cppdbg adapter.
