Describe the bug

Currently TanStack Router supports dynamic path segments in the form /$var/. However it is sometimes useful to have a static prefix (or suffix) that is used as part of the matching. For example youtube.com/@ChannelName.

This is a feature request for Router to support the form /prefix$var/ (or some other way of having a static prefix mixed with a dynamic variable). Optionally it would be nice to also support suffixes, perhaps in the form /prefix$var$suffix/?

Your Example Website or App

https://stackblitz.com/edit/tanstack-router-jwzga9?file=src%2Fmain.tsx

Steps to Reproduce the Bug or Issue

new Route({
  path: '/prefix$var',
  component: function User({ useParams }) {
    const params = useParams();
    return <div className="p-2">Hello {params.var}!</div>;
  },
});

This will not be recognized as a dynamic route and var will not be available in params

Expected behavior

var would be available in params
