- 电池按九种风格画在菜单栏，充电中带闪电，电量低于 20% 按“高负载时着色”变红；点击弹出电池详情，主窗口同名页面复用同一视图，历史页多了电池电量曲线 - 历史库加 battery 列（旧库首次打开时 ALTER TABLE 迁移），HistoryRecorder 单独查最近 24 小时电量供弹窗使用 - BluetoothController 按需轮询蓝牙设备电量：弹窗 / 页面开着每分钟，菜单栏需要时每 5 分钟；本机信息页的蓝牙卡片改用它 - 没有电池的 Mac 上电池项目改为显示电量最低的蓝牙设备；「设置 · 菜单栏」新增“蓝牙设备电量低时提示”开关（同步文档一并带上） - README、架构说明、更新日志与译文同步
