 * TODO(#1198): remove when fetch over HTTP/2 is safe on Node 26. Remove when all
 * of these are true:
 *  - nodejs/node no longer creates an orphan ClientHttp2Stream when a client
 *    session gets HEADERS for a stream id it already reset. Repro: abort a fetch
 *    before its response headers, then idle 4s on Node 26. Fixed when the
 *    process survives.
 *  - modelcontextprotocol/typescript-sdk#2526 is closed.
 *  - pi-coding-agent's CLI drops `allowH2: false` from its http-dispatcher.
 * Same workaround as pi's CLI and typescript-sdk#2526: HTTP/1.1 only.
