Search GitHub PR reviewers beyond the first page

[moinmir]

T3 Code’s GitHub reviewer picker fetches the first 100 assignable users. Its search box only filters those loaded candidates, so repositories with more than 100 assignable users can have people missing from search results.

Could the picker search GitHub when the initial candidate list is incomplete? GitHub’s API supports filtering assignable users by name or login.

This would add API calls while searching an incomplete list, with a short debounce to limit requests.

Would maintainers support this direction before implementation?
