- app.js: 提取 registerBusListeners 方法，新增自动重连机制（3次上限） - configureDevice: bus 订阅迁移至 onShow，deviceConnect 按步骤区分处理逻辑 - configureDevice_2: setUserInfo 兼容 WIFISUCCESS 状态，WXML 覆盖六态 - configureDevice_3: 新增 reInitWifi 方法，最小化后重置 WiFi 列表 - replaceNetwork: 订阅迁移至 onShow，修复 selectComponent 空指针 - replaceNetwork_3: 修复 domain1 配网参数引用错误 - userInfo: 订阅迁移至 onShow，setUserInfo 兼容 WIFISUCCESS - searchDevice: 移除 onLoad 重复初始化，统一由 onShow 处理 - 所有 BLE 页面统一 onHide/onUnload 清理：resetReconnectCount + setGlobalData(null) + stop() Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
