feat: AC 三合一设备支持 + 新增 Plug/Gateway 驱动 + Cover 结构化重构

**AC 驱动增强**
- 支持 thermostat + air-conditioner + air-fresh 多服务三合一设备，属性跨服务合并解析
- 新增 specResolver.findValListInService/findInService/hasService/serviceShortName 方法
- 移除 KindThermostat，heater/electric-blanket/thermostat 重新归类为 KindAirConditioner

**Cover 窗帘重构**
- CoverProps 结构化：Position/Status/Fault 分离
- SetPosition 优先写 target-position，回退 current-position
- OnPropsChanged/FetchProps 支持多属性同步刷新

**新增设备类型**
- Plug 驱动：插座/插头，支持开合、在线状态、属性变更订阅
- Gateway 驱动：网关设备类型识别
- miot/miot_errors.go：新增 MIoT 云端错误码定义

**MIoT 客户端健壮性**
- SetProp 空结果视为失败；设备被移除或离线时自动刷新设备列表
- GetDevices 的 has_more 改用 parseBool 严格解析
- MIPS SubscribeMany 批量订阅减少往返
- matchURN 改为按段精确匹配，避免 tofan 误匹配 fan

**Bridge**
- 移除 Thermostat case，Cover 改用结构化 CoverProps
- 新增设备创建后自动订阅属性变更

**其他**
- 日志整体 Info → Debug 降噪
- .gitignore 忽略 /.codebuddy/memory
- 更新 devices_test 与 08_adv_filter_classify 示例
