CarpenterTreeView<T> class final

Controlled hierarchical collection with keyboard navigation and DnD. Pointer selection also focuses the tree, so subsequent keyboard navigation and ancestor command shortcuts operate on the selected row. Selection itself remains controlled by selectedIds and onSelectionChanged.
