pub(crate) async fn serve_stdio(server: FutuServer) -> Result<()>Expand description
stdio 模式：MCP 客户端启动子进程，stdin/stdout 传协议帧
v1.4.90 P0-A: uses resilient_stdio() instead of rmcp::transport::stdio()
— a malformed JSON line (e.g. {"price": Infinity} from an LLM client)
now produces a -32700 Parse error response instead of exit(0)-ing the
entire server. See crates/futu-mcp/src/transport.rs for full background.
