/**
 * Row-resize Svelte action - drag the bottom edge of a row to grow /
 * shrink it. Pair with a function-valued `rowHeight` prop so the grid
 * reads per-row heights from a reactive store.
 *
 * The action is OFF until a consumer attaches it AND a row-header
 * gutter cell exists in each row. A row-header cell is either the
 * grid's built-in row-number gutter (enable `showRowNumbers`) or any
 * TD tagged with the `sv-row-gutter` class (set
 * `cellClass: 'sv-row-gutter'` on a custom gutter column).
 *
 *   <script>
 *     let heights = $state<Record<number, number>>({})
 *     let resizeOn = $state(false)
 *     const rowHeight = (i: number) => heights[i] ?? 32
 *     function onResize(i: number, h: number) { heights = { ...heights, [i]: h } }
 *   </script>
 *
 *   <div use:rowResize={{ onResize, disabled: !resizeOn }}>
 *     <SvGrid columns={[{ field:'rn', cellClass:'sv-row-gutter', ... }, ...]}
 *             rowHeight={rowHeight} ... />
 *   </div>
 *
 * Visual: the strip sits along the bottom edge of the row-header
 * cell, 5px tall, transparent by default, accent-tinted on hover -
 * matching the column resize handle's look. Cursor is `row-resize`.
