UseTableRowExpansion

Hook that returns a TablePlugin which expands a full-width detail panel below a row, rendered by the consumer via renderExpanded(item). Adds a leading chevron column and a right-click "Expand/Collapse row" action; the consumer owns the expandedKeys set. The panel spans the row but starts its content at the first column, past the chevron, so detail lines up with the labels above it; the inset follows the table density. Use it for master-detail rows (order details, forms, charts, nested tables). For hierarchical data where child rows reuse the parent columns, use useTableTreeData + useTableTreeState instead.
