Question about using `forkScoped` vs `fork` for managing fiber lifecycles in Effect Typescript

const workFiber = Effect.gen(function* () {
  const heartbeatFiber = yield* heartbeat.pipe(
    Effect.repeat(Schedule.spaced("5000 millis")),
    Effect.forkScoped,
  );
  yield* doWork().pipe(Effect.ensuring(Fiber.interrupt(heartbeatFiber)));
}).pipe(Effect.scoped);
