   * Utility function to handle redirects returned from an action or loader.
   * Normally, a redirect "replaces" the navigation that triggered it.  So, for
   * example:
   *
   *  - user is on /a
   *  - user clicks a link to /b
   *  - loader for /b redirects to /c
   *
   * In a non-JS app the browser would track the in-flight navigation to /b and
   * then replace it with /c when it encountered the redirect response.  In
   * the end it would only ever update the URL bar with /c.
   *
   * In client-side routing using pushState/replaceState, we aim to emulate
   * this behavior and we also do not update history until the end of the
   * navigation (including processed redirects).  This means that we never
   * actually touch history until we've processed redirects, so we just use
   * the history action from the original navigation (PUSH or REPLACE).

   * used to emulate React error boundaries during SSr by performing a second
   * pass only down to the boundaryId.

   * redirect response is returned or thrown from any action/loader.  We
   * propagate that out and return the raw Response so the HTTP server can
   * return it directly.

  /**
   * The queryRoute() method is intended for targeted route requests, either
   * for fetch ?_data requests or resource route requests.  In this case, we
   * are only ever calling a single action or loader, and we are returning the
   * returned value directly.  In most cases, this will be a Response returned
   * from the action/loader, but it may be a primitive or other value as well -
   * and in such cases the calling context should handle that accordingly.
   *
   * We do respect the throw/return differentiation, so if an action/loader
   * throws, then this method will throw the value.  This is important so we
   * can do proper boundary identification in Remix where a thrown Response
   * must go to the Catch Boundary but a returned Response is happy-path.
   *
   * One thing to note is that any Router-initiated Errors that make sense
   * to associate with a status code will be thrown as an ErrorResponse
   * instance which include the raw Error, such that the calling context can
   * serialize the error as they see fit while including the proper response
   * code.  Examples here are 404 and 405 errors that occur prior to reaching
   * any user-defined loaders.
   *
   * - `opts.routeId` allows you to specify the specific route handler to call.
   *   If not provided the handler will determine the proper route by matching
   *   against `request.url`
   * - `opts.requestContext` is an optional server context that will be passed
   *    to actions/loaders in the `context` parameter
