The snapshot streamed tables by name and rows by pk_json text, so a child
(or a self-reference whose parent's key sorts later) reached the receiver
first, failed its immediate FK check and was dead-lettered - permanently,
since the snapshot's watermark and ack covered it (LocalDb-002).
Sender: stream referenced tables first (Kahn order, name tie-break).
Receiver: SnapshotApplier defers rows that fail only
SQLITE_CONSTRAINT_FOREIGNKEY, retries them as rows land, and dead-letters
true orphans at SnapshotComplete. Delta path unchanged; wire unchanged.
