feat: IoT 知识库 + 设备查询控制方式改造

- cyrene_persona.yaml: 新增 smart_home 配置段，定义全屋智能家居知识库、设备能力、房间布局和控制规则
- loader.go: 新增 SmartHomeConfig/RoomConfig/DeviceConfig 结构体解析 YAML
- injector.go: BuildSystemPrompt 自动注入智能家居知识库和控制规则
  - 新增 buildSmartHomeKB() 和 buildControlRules() 方法
  - 新增 joinStrings() 辅助函数
- main.go: 移除 shouldQueryIoT 关键词门控，始终注入 IoT 设备状态到上下文
  - 移除未使用的 strings 导入
- IoTStatusBar.tsx: 对所有用户开放 IoT 状态面板（而非仅 dev 模式）
