 * Iterative force-directed layout via d3-force (optional peer dependency).
 * Each `next()` advances one simulation tick and yields a {@link LayoutFrame}
 * (top-left node positions by id + remaining `alpha`); the caller owns pacing
 * (e.g. one tick per animation frame via {@link applyLayoutFrame}) and
 * cancellation (stop iterating). The generator's return value is the settled
 * {@link VisualGraph}.
 *
 * - Deterministic: `options.seed` drives d3's `randomSource`; the same seed
 *   always produces the same layout.
 * - `options.isFixed` pins nodes at their current position (d3 `fx`/`fy`).
 * - Hierarchy is ignored (force layouts are flat); per-edge `mode` is
 *   irrelevant (forces are symmetric).
 *
 * @example
 * ```ts
 * import { genForceLayout } from '@statelyai/graph/layout/d3-force';
 * import { applyLayoutFrame } from '@statelyai/graph/layout';
 *
 * for (const frame of genForceLayout(graph, { seed: 42 })) {
 *   applyLayoutFrame(graph, frame);
 *   render(graph);
 * }
