- WrapUDPConn, WrapPacketConn, WrapListener: add nil guards for pc/ln params - NewGRPCPlugin: return no-op observer instead of nil on connection error - gRPC plugin: fix resource leak by wiring Close() through observerWrapper and service.Close() lifecycle - Both plugins: log unknown event types instead of silently dropping them - httpPlugin: remove dead nil check for always-non-nil client field - Stats.Reset: update core interface doc to match implementation behavior - Add doc comments to all exported symbols across the observer package
