Called once the handler has received and signature-validated a record and
imported its CAR into the blockstore. Implementations own the durable side:
recording the work, pinning the content, and publishing the record to
routers. The handler awaits this before closing the stream as success, so it
should return promptly once it has durably recorded enough to recover the
work, running the slow pin and DHT publish in the background.
