function GetContextMenuActions

virtual void GetContextMenuActions(

) const override

Replaces the engine's Split/Recombine Struct Pin context entries with ones that route through USMPropertyGraph::SplitResultPin / RecombineResultPin / SplitSubPin / RecombineSubPin so the plugin's bSplit flag, SplitPropertyGuids, and NestedSplitPaths stay in sync with the pin tree. Engine's own handlers hit GetDefault() directly and bypass schema polymorphism, so overriding SplitPin / RecombinePin would be a no-op here; replacing the menu entries is the only hook that catches the user path.
