type error when passing number to `Link.params`

Which project does this relate to?

Router

Describe the bug

despite the docs: https://github.com/TanStack/router/blob/410fdf808d959de0efb92a9d1339048a7cd053f1/docs/router/framework/react/guide/path-params.md?plain=1#L409-L414

putting numbers in params on Link component gives type error

Your Example Website or App

https://stackblitz.com/edit/github-ynvn4fan?file=src%2Froutes%2F__root.tsx

Steps to Reproduce the Bug or Issue

1. create any route with params e.g $foo.bar.tsx
2. <Link to="/$foo/bar" params={{ foo: 3 }}>
3. get type error that you cannot assign number to string

Expected behavior

type works like the docs
the numbers do get auto-stringified, but the type error makes everything cumbersome (have to wrap in String)

Additional context

for some reason this error isn't reproducible on tanstack/router repo.

Start with the linked StackBlitz reproduction and the React path-params documentation at the referenced lines, using a route such as $foo.bar.tsx and Link with params={{ foo: 3 }}. Compare its generated types with the TanStack Router repository, where the issue says the problem is not reproducible; done means numeric Link.params values type-check while retaining the documented auto-stringification behavior.
