refactor: 重大架构升级 — HomeID/RoomID int64化 + 设备驱动重构 + 结构化日志

主要变更：

**类型系统重构**
- HomeInfo.ID/RoomInfo.ID/HomeID 从 string 改为 int64，json tag 使用 ,string
- GetHome/GetRooms/GetRoomDevices 接口同步修改
- 新增 int64FromStr 工具函数，更新 parseHomeInfo 解析逻辑

**新增 Speaker 设备**
- 新增 KindSpeaker 类型
- classify 映射覆盖 speaker/bluetooth-speaker/alarm-clock/media-player/playback/music

**设备驱动重构**
- AC 驱动彻底重写：从硬编码常量改为基于 SPEC ValueList 的动态 valMapper
- 所有设备(Fan/Humidifier/Light/OccupancySensor/Switch/TempHumiditySensor/Thermostat/Vacuum/WaterHeater/Cover)新增 GetState() 和 FetchState(ctx) 接口
- base.go 新增 specResolver.format() 方法

**MIoT 模块增强**
- MIoTClient 新增 homeIDs 字段，支持按家庭过滤设备
- RefreshDevices 支持 homeIDs 参数
- SpecStdLib 引入 logger.Logger，log.Printf 全部迁移为结构化日志

**其他**
- Config 新增 RedirectURL 和 HomeIDs 字段
- AuthInfo.ExpiresIn 类型从 int 改为 int32
- UUID 生成简化为 hex.EncodeToString
- 新增 github.com/sirupsen/logrus 依赖
- .gitignore 新增 examples/*/data/ 忽略规则
- 删除已提交的 config.json 敏感配置
