 * Lay out a graph with ELK (via `elkjs`, an optional peer dependency).
 * Pure: returns a new {@link VisualGraph} with node positions/sizes, routed
 * edge `points`, and computed edge label rects (edge `x`/`y`/`width`/`height`).
 * Hierarchy (`parentId`) and ports are first-class — ELK is the engine of
 * choice for compound and port-aware graphs. Child node coordinates are
 * relative to their parent (matching xyflow's convention).
 *
 * @example
 * ```ts
 * import { getElkLayout } from '@statelyai/graph/layout/elk';
 *
 * const laidOut = await getElkLayout(graph, {
 *   algorithm: 'layered',
 *   measure: (node) => measureText(node.label),
 * });
