> When a replication source terminates while a WAL entry batch is in flight, its buffer quota can remain accounted indefinitely.
> ReplicationSourceShipper.shipEdits polls a WALEntryBatch from the reader queue. The buffer quota is released after successful shipping through postShipEdits; if the worker stops before successful shipping, the batch is no longer in the reader queue and cleanup cannot release its quota.
> Track whether the polled batch was released by successful shipping and release the batch quota after the shipping loop when it was not successfully shipped. Add a regression test for a stopped shipper holding an in-flight batch.
