 * Replace node `nodeId` in `plan` with the nodes of `subPlan`, flat (no nesting):
 * - sub-plan node ids are namespaced `${nodeId}:${id}` (collision-safe);
 * - sub-plan ROOT nodes (no intra-sub deps) inherit the replaced node's
 *   `dependsOn` AND `needsInput`;
 * - consumers that depended on `nodeId` now depend on the sub-plan's TERMINAL
 *   nodes (sub nodes nothing else in the sub-plan depends on).
 * Returns a new DagPlan (no mutation of the input).
