 * Columns tool panel — a side panel that manages the grid's columns (show/hide,
 * search, pin, reorder) and drives row grouping, aggregation, and pivoting via
 * drag-and-drop zones. It reads and writes the grid's reactive APIs
 * (`columns`, `groupBy`, `aggregations`, `pivotRows`/`pivotOn`/`pivotValues`),
 * so every action maps to an existing capability. Mount beside the grid and set
 * its `grid` property.
 *
 * Drag a column from the list into **Row Groups**, **Values**, or (in pivot
 * mode) **Column Labels**. The pivot-mode toggle repoints the zones at the
 * pivot APIs.
