Merging should be blocked on tests passing.

I really want to sarcastically ask if you can break this into smaller PRs because this is too large 🙃

@alexlaurinmath is this meant to be merged into a single commit like this?

I see 7 commits in this PR, most of them are merges of the copybara branch. I thought this was preserving history?

✅ Scanned list of packages
✅ Scanned for internal identifiers
✅ Scanned for copy config files / README inclusion

I wasn't able to get history preservation to work. I think we see multiple commits because I'm using the same branch without deleting it? If this becomes a problem I'll either delete the branch or use a different one.
