Option to address "clutter"

We may want to consider a means to filter out repositories that should not go through the [GitHub archive process](https://docs.github.com/en/repositories/archiving-a-github-repository/archiving-repositories), i.e., they wouldn't be read-only, but perhaps aren't repositories that we want highlighted in the Catalog. This could be just a re-sort to push them to the end. Examples are no longer maintained projects that should still be searchable or new projects with limited content (this would be a temporary re-sort).

The issue names no files, tests, or entry points. Start by tracing how the Catalog receives and orders repositories from the GitHub and Hugging Face APIs. Define how projects with limited or inactive content are identified, how they remain searchable, and what ordering or filtering behavior counts as done.
