 * Resume a suspended continuation by re-triggering the original effect.

 * re-dispatches the original effect (captured in `snapshot.effectName` /
 * `snapshot.effectArg`) to the registered host handlers. The handler then
 * calls `resume(value)`, `fail()`, or `suspend()` as normal.
 *
 * Throws if the snapshot has no captured effect (i.e. suspension occurred
 * outside of an effect handler, such as in a parallel/race branch).
 *
 * Always resolves — never rejects. May return `completed`, `suspended`
 * (if the handler suspends again), or `error`.
 *
 * ```typescript
 * const { snapshot } = suspendedResult
 * const next = await retrigger(snapshot, { handlers })
