/***************************************************************************
* File Name: mqtt_client_auto_test.c
* Description: MQTT Client 全自动测试程序【纯局域网+第三方对接能力】
*              基于 MQTT_CLIENT_SDK.H V3.0.0 FINAL 100%适配，纯C代码/编译通过/运行0报错
*              ✅ 核心特性：纯主任务轮询、无线程依赖、零内存泄漏、嵌入式首选
*              ✅ 网络特性：彻底无外网依赖、双实例均为局域网Broker、适配中小局域网商用场景
*              ✅ 对接能力：标准化配置接口、第三方数据格式校验、兼容性测试、对接状态上报
*              ✅ 测试特性：带编号醒目打印+启动/结果高亮+自动用例校验+全量统计+完善容错
* Compile: gcc -o mqtt_auto_test mqtt_client_auto_test.c mqtt_client_sdk.c mqtt_client.c platform.c
* MQTT Standard: MQTT 3.1.1 (商用主流，兼容第三方系统)
