63 * Wraps a native-engine call with a hard timeout. A hung native call (e.g.

64 * a stuck getDeviceList/usync query) was observed blocking the whole

65 * process — including the unrelated MQTT connection — for 80+ seconds,

66 * taking down the entire bot (all threads, not just the one send). This

67 * makes any single native call fail fast instead of hanging indefinitely.
