  The `{ spawn }` variant of [`ForkIsolatedOptions`](https://adk.nht.io/api/batteries/isolation/child_process/type-aliases/ForkIsolatedOptions) — spawns via a
  caller-supplied [`ChildResolver`](https://adk.nht.io/api/batteries/isolation/child_process/type-aliases/ChildResolver) instead of this module's own `fork()`.
