MQTT协议示例AIWROK版 - B2B网络软件

/**
* MQTT 协议示例 - AIWROK 版
*
* 使用 Eclipse Paho Java 客户端实现 MQTT v3.1.1 连接
*
* v5 说明：dex 为官方 Paho 1.2.5 源码修补版（2026-08-29 重建）：
* 1. LoggerFactory 资源包查找加保护，默认使用 MockLogger（无操作日志）
* → 修复 dex 环境下 ResourceBundle.getBundle 必抛 MissingResourceException
* 2. NetworkModuleService 加内置协议工厂兜底（tcp/ssl/ws/wss）
* → 修复 dex 无 META-INF/services 导致 "no NetworkModule installed for scheme tcp"
* 3. 脚本不再需要任何运行时反射补丁
* 支持：发布/订阅模式、QoS 0/1/2、自动重连、遗嘱消息、心跳保活
*
* MQTT vs WebSocket 区别：
* MQTT 是轻量级发布/订阅消息协议，适合 IoT/移动端
* 比 WebSocket 更省电、更省流量，支持 QoS 消息质量保证
* 支持主题(Topic)订阅，消息路由更灵活
*
* 依赖加载（自动，无需手动操作）：
* dex 文件放在 H5HTML/插件/ 目录，AIWROK 的 loadDex 自动加载
* loadDex 只从"插件"目录加载，且需要 .dex 格式（不是 .jar）
*
* dex 文件已随工程打包在：H5HTML/插件/paho-mqtt.dex
* 如果插件目录没有 dex，自动从代码目录的 paho-mqtt-dex-b64.js 还原
*
* 使用方法：
* 1. 修改 CFG 中的 broker 地址、端口、用户名密码
* 2. AIWROK 中直接运行本脚本
* 3. 日志窗口查看连接状态和收发消息
