 * If there's special convention like (...) or @ in the page path,
 * Give it a unique hash suffix to avoid conflicts
 *
 * e.g.
 * /opengraph-image -> /opengraph-image
 * /(post)/opengraph-image.tsx -> /opengraph-image-[0-9a-z]{6}
 *
 * Sitemap is an exception, it should not have a suffix.
 * Each sitemap contains all the urls of sub routes, we don't have the case of duplicates `/(group)/sitemap.[ext]` and `/sitemap.[ext]` since they should be the same.
 * Hence we always normalize the urls for sitemap and do not append hash suffix, and ensure user-land only contains one sitemap per pathname.
 *
 * /sitemap -> /sitemap
 * /(post)/sitemap -> /sitemap
