Usage

State management companion for useTableTreeData. Owns the expanded set (controlled or uncontrolled) and flattens nested data into the visible row array; collapsed subtrees are unmounted, not hidden, so the table body contains exactly the visible rows. Returns expandAll / collapseAll helpers, the aggregate isAllExpanded state (true/false/indeterminate) for a header expand-all control, and a ready-to-use plugin for the tree. Note: because collapsed rows unmount, local component state inside collapsed subtrees is lost on collapse; lift state that must survive.

Nested rows are flattened into the visible rows, and the expanded set lives in the hook. The header control expands every branch, and a row click expands a node that has children.
