Create a lazy, serial worker session. Only one transferred request is active;
queued batches stay caller-owned until dispatch. Cancelling active work
settles the caller immediately and gives the worker a bounded window to
acknowledge the cancellation; a worker that misses the window is retired so a
non-cooperative operation cannot escape bounds.
