Sync substrate for PowDB.
This crate is intentionally below the query layer. Its first responsibility is
retaining durable WAL records as immutable replication-unit segments so future
embedded replicas and read replicas can bootstrap from snapshot + tail without
making powdb-query distribution-aware.
