ContextMenuDelegate class abstract

Abstract strategy for handling secondary clicks (right-click) on tree nodes.

Why: Decouples the tree's logic from specific UI implementations (Material, Cupertino, MacosUI).

Implement this to show custom menus or use MaterialContextMenuDelegate for a standard popup.
