按照 TOKEN_REFACTOR.md / FIX_CONFIG.md 方案重构核心层： - miot: Init() 优先读 storage token，新增 RefreshAuthInfo() 和刷新回调 - xiaomi: Config 改用 AuthInfo 结构体（含 UUID/UID/DataDir/OnTokenRefreshed） - xiaomi: NewClient(ctx, Config) 新签名，新增 RefreshToken()，后台自动刷新 - xiaomi/devices: 设备控制接口重构 - 新增示例 12_ac_subscribe，其余示例适配新 Config
