Secrets-011: HandleAnnounceTick pipes the manifest read back to the actor and publishes the
announce from the mailbox with Self as sender. Under a genuinely async store it used to publish
from a pool continuation with NoSender, so every peer replied to deadLetters; a faulted manifest
read was dropped silently and is now logged.
Secrets-012: the exchange's push rows, the pull reply and the pull request are split into
messages of at most 64 KB (measured with the wire encoding), half Akka.Remote's default 128000-byte
frame, so a cold node converges against a large store. A single over-budget row is still sent
alone; the manifest announce is not split (documented in clustered-secrets.md).
