fix: handle io.EOF in Start and Reset gRPC streams

Start() and Reset() client methods treated io.EOF from stream.Recv() as an error, unlike Build(), SnapshotSave(), and other streaming methods which handle it as clean stream termination. This caused intermittent stream: EOF errors on reset and start.
