- Introduced cluster node management with `clusterNode` and `clusterNodesEnvelope` types. - Added failover handling for reconnection failures with configurable threshold (`homeReconnectFailoverThreshold`). - Implemented node switching and dynamic cluster target updates. - Enhanced Redis client management with centralized locking for concurrency safety. - Updated configuration refresh logic to prioritize the best cluster node. - Improved debug logging for reconnect failures and node switching.
