Router

Describe the bug

Problem

router.routesByPath is defined as RoutesByPath<TRouteTree> which includes trailing '/' for index routes. However this does not match the runtime type which removes trailing slashes.

Description

Given the following structure:

foo/
└── bar/
    ├── index.tsx
    ├── route.tsx
    └── __root.tsx

generates:

export interface FileRoutesByFullPath {
  '/bar': typeof fooBarRouteRouteWithChildren
  '/bar/': typeof fooBarIndexRoute
}

but in:

https://github.com/TanStack/router/blob/4568b38b69b5a649484a8168f4765de97c10f193/packages/react-router/src/router.ts

       if (!childRoute.isRoot && childRoute.path) {
          const trimmedFullPath = trimPathRight(childRoute.fullPath)
          if (
            !(this.routesByPath as any)[trimmedFullPath] ||
            childRoute.fullPath.endsWith('/')
          ) {
            ;(this.routesByPath as any)[trimmedFullPath] = childRoute
          }
        }

we can see that the trimmed path is the key that is used for the object at runtime.

Not quite the same, almost the inverse. Probably fixed in the same area though.
