Migrate the local database layer from @libsql/client to the official @tursodatabase/database package. The new embedded Turso engine provides improved local performance, concurrent writes (MVCC), and built-in encryption at rest. Preserve existing shard, vector-search, migration, backup, and recovery behavior, and verify compatibility with F32_BLOB and DiskANN vector indexes before making it the default backend.
