Delivers one batch from the process's telemetry store. The batch goes back to
the store unless the delivery reported success — a defect included — so the
next call carries the same events again; a delivery failure is ignored and
never fails the caller. Kept for the flows that instrument a sequence and
must not see a delivery error. An empty store sends nothing — it no longer
posts an empty upload.
