Add Maya-style prim editing to SceneHierarchyPanel

- Inline rename: double-click prim label or F2 to edit name in-place; Enter commits, click-away or Esc cancels (undo-able) - Drag-and-drop reparent: drag any prim onto another to make it a child; invisible root drop zone below tree to reparent to stage root (undo-able) - Ctrl+G group: creates Xform group at common parent, reparents selection under it; filters descendant duplication; selects new group (undo-able) - Delete key shortcut: opens existing remove-prim modal when panel focused - Context menu: Rename (F2) and Group (Ctrl+G) items added - Three new undo-able commands using UsdNamespaceEditor (USD 25.05): RenamePrimCommand, ReparentPrimCommand, GroupPrimsCommand Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
