LGTM since this one is fully moved to the new repo and I don't think we will be releasing google-genai from this repo again

I wonder if we can just delete this code altogether tbh. I don't remember why we didn't yet. There is a note in the README about security patching. But I imagine we would just do patch releases off the old branch and not main

Hi @xrmx — just a friendly reminder that this pull request is waiting on you. The dashboard status comment has the open items and is kept current.

• Replying is enough to hand it off — answer, explain why no change is needed, or ask a follow-up. The dashboard routes it onward once nothing on the list is waiting on you.
• To hand it back for any other reason, including the dashboard getting this wrong, comment /dashboard route:reviewers.

@xrmx chatted with folks offline and we agreed to just delete. Do you want me to send a separate PR for this, or just update this one?
