Nobody else will be working on it before then so that's ok. Thanks!

Chiming in that if @faradaytrs has not started on this, or if you are not sure about your availability, that I would be happy to work on this instead! I sketched out a few approaches a while back, and I have time over the next month to poke at it ✍️

Aside: I will have some open questions about the implementation. For example, since catalogs are managed in pnpm-workspace.yaml instead of package.json, and the npm manager focuses onpackage.json-shaped package files, I wonder if it makes sense to implement a dedicated pnpm-catalog manager. The npm manager does read pnpm-workspace.yaml as a config file, but has not needed to treat it like a package file, so far. Anyway, I can leave some of these notes in a draft PR, just to avoid adding noise to the issue. Thank you for all the work on Renovate over the years 😊

The npm manager in renovate can return additional package files so I think it's probably best to handle it in the existing manager

npm module is already too big. I think it's better to have a separate manager for this.

We will be moving out yarn and pnpm from the npm module someday so it aligns with that refactor too I think.
