feat: 重写为 GPUI 原生桌面应用并接入 Gitea 软件包发布

- gpui-kit 0.6 原生 UI：连接管理、消息流/日志、发布预设、全局变量、设置、阿里云连接预设、原生 Logo - MQTT 5.0/3.1.1 引擎（rumqttc，TCP/TLS/WS/WSS），独立 tokio runtime + 事件泵，真实 broker 端到端测试 - 连接表单：保存前可一键测试连接（宽松校验，自动生成临时 Client ID），高级属性（认证/MQTT 5 属性/遗嘱）按需折叠显示，WS 路径仅 WS/WSS 显示 - bug 修复：Hex 奇数长度显式报错、测试连接唯一 Client ID、Base64/Hex 发布发送真实字节、v5 发布记录携带 Content-Type/用户属性、预设应用清除旧 Content-Type、模板时间基准统一；补 8 个单元测试 - Gitea 发布：Generic Package 上传脚本（bash/PowerShell）+ Actions release 工作流（tag 触发，双平台构建），README 使用说明
