Durable local state and peer convergence

PGlite persists normalized entities and explicit queue/checkpoint state in a local PostgreSQL-compatible database. Loro adds CRDT convergence as a companion package rather than a core dependency. The sync bridge projects provider events into a chosen graph store and suppresses inbound echo.

Use deterministic loopback networks to test offline ordering and conflicts; use the WebSocket channel integration to test real disconnect and snapshot recovery. Neither proof substitutes for a production authorization model.
