TreeViewNode<T> class
A node in the compatibility TreeView constructor.
Use TreeView.model with bubbles.TreeItem when expansion, selection, and
viewport state must be shared with another host. This class remains useful
for concise, display-oriented trees and preserves the original TreeView
API.
Named TreeViewNode to avoid collision with the bubbles TreeNode
interface from package:artisanal.
