/**
 * Lay out a graph with Graphviz (via `@hpcc-js/wasm-graphviz`, an optional
 * peer dependency). Pure: returns a new {@link VisualGraph} with node
 * positions/sizes, routed edge `points` (`routing: 'splines'` — Graphviz
 * b-spline control points, tail → head, endpoints included), and computed
 * edge label rects (edge `x`/`y`).
 *
 * Node sizes are resolved via {@link getNodeSize} and passed to Graphviz as
 * fixed sizes, so layout never depends on Graphviz's own text measurement.
 *
 * Notes:
 * - Compound graphs (`parentId`) are not supported — use `getElkLayout`, or
 *   `getFlattenedGraph()` the graph first. (Graphviz clusters: planned.)
 * - In a directed graph, edges with `mode: 'undirected'` are laid out as
 *   directed but drawn without arrowheads (`dir=none`); in an undirected
 *   graph, per-edge `mode: 'directed'` overrides are ignored (DOT `graph`
 *   has no directed edge operator).
 * - `options.seed` maps to the Graphviz `start` attribute (used by the
 *   randomized engines neato/fdp/sfdp; ignored by deterministic engines).
 * - `options.constraints.layer` maps to `{ rank=same; … }` groups (`dot`
 *   engine only — the other engines have no rank concept).
 *
 * @example
 * ```ts
 * import { getGraphvizLayout } from '@statelyai/graph/layout/graphviz';
 *
 * const laidOut = await getGraphvizLayout(graph, {
 *   engine: 'dot',
 *   measure: (node) => measureText(node.label),
 * });
 * ```
