Storage Sync

Synchronize memories between Turso (durable) and redb (cache) storage layers.

When to Sync

1. On startup - After system initialization
2. Periodic - Scheduled background sync
3. Cache staleness - When redb appears outdated
4. Recovery - After storage failures
5. Manual trigger - When explicitly requested

Sync Process

1. Check connection health:

   turso_client.ping().await?;
   redb_env.check_integrity()?;
