## Title

    Proposed fix: [undici v8] HTTP/2 enabled by default via ALPN — calls through h2-capable LBs/proxies now surface 'HTTP/2: "GOAWAY" frame received with code N' SocketErrors; set allowH2: false to restor

## Body

    Recommended action: If you depend on HTTP/1.1 behavior or see GOAWAY failures, set allowH2: false on the Client/Agent used by your SDK; otherwise retry idempotent requests on GOAWAY SocketErrors.
    
    Option: Pin HTTP/1.1 [evidence: official_recommended_action]
    Applies when: See trigger
    Steps:
    1. new Agent({ allowH2: false }) and pass it as the fetch dispatcher / SDK fetchOptions.
    Expected: Error no longer occurs
