…le and TreeItemPersonaLayoutContextValues Required for the headless layer to compose avatar context values without importing internal module paths. Co-Authored-By: Claude Sonnet 4.6 <[email protected]>
…family Adds headless wrappers for the full react-tree component surface: - Tree (context values via useTree + useTreeContextValues) - FlatTree (context values via useFlatTree + useFlatTreeContextValues) - FlatTreeItem (re-export of FlatTreeItem — a typed alias for TreeItem) - TreeItem (context values via useTreeItem + useTreeItemContextValues) - TreeItemLayout (simple single-arg render, no context values) - TreeItemPersonaLayout (context values via useTreeItemPersonaLayout + useTreeItemPersonaLayoutContextValues) Also re-exports useHeadlessFlatTree and related types for consumers building virtualized flat trees.
