Description
Core orchestrator that processes the sync queue whenever network connectivity is available. Schedules periodic background tasks via the WorkManager Adapter, dequeues pending operations sequentially, dispatches REST API calls, and updates queue item status on success or failure. Applies exponential backoff with jitter for retries and flags items exceeding a configurable retry threshold for user review.
