WebRtcHttpMessage class
WebRtcHttpMessage: HTTP over WebRTC 消息协议
将 HTTP 语义封装到 WebRTC DataChannel 传输 合并了请求管理（request_id）和完整的 HTTP 协议语义
协议栈层次： Layer 3: WebRtcHttpMessage (本层) - HTTP over WebRTC Layer 2: ALocalSample (Protobuf) - 业务消息封装 Layer 1: RtcData - 传输协议
使用场景：
- 文件列表查询: GET /files/list?path=/home
- 文件上传: POST /files/upload
- 文件下载: GET /files/download?file=xxx
- 设备控制: POST /device/control
