Breaking change caused by "fix: fullpath handling" PR

Which project does this relate to?

Router

Describe the bug

#6404 led to a large amount of type errors in our codebase since a trailing / was added to our routes.

Further, we now have a weird UX where the keys of FileRoutesByFullPath are different than the keys of FileRoutesByTo:

Given this distinction, we end up with weird calls to navigate and related apis like the one below

Steps to Reproduce the Bug or Issue

Generate the route tree prior to b42f84a, ensuring you have one or more index.tsx route files.

Note that they won't have a trailing /

Now generate again but with b42f84a

Note that now those routes have a trailing /
