## Communication Protocol

- **Standard**: 全面转向 **JSON-RPC 2.0** 作为 APP 与 Bridge 之间的默认通信协议。
- **Client Implementation**: `GatewayAcpClient` 与 `GatewayRuntime` 已完成健壮性升级，支持自动识别 JSON-RPC 2.0 报文。
- **Compatibility**: 当前处于混合过渡期，Bridge 响应报文会同时包含 JSON-RPC 2.0 字段（`result`/`error`）与 Legacy 字段（`ok`/`type`/`payload`），确保旧版逻辑不会崩溃。
