LLM Commit in upstream `master`?!

Hello,

I have been made aware that in upstream master we have a commit co-authored from Claude Fable 5?! How is this possible? The commit in question is: 3735384b193617a912fbf6d25844041ed288bf28. The author and committer is Yuan Fu.

There was a _clear_ policy from GNU that until a policy is settled there shall be no commits or patches from a LLM. This had been discussed extensively in emacs-devel and in gnu-prog-discuss. This is a serious breach of trust and accountability. I hope this commit can be reverted soon.

Also, to note that the commit actually makes non-trivial (legally significant) changes. So, this is an absolute _risk_ copyright wise to us if we keep this code.

Needless to say, this has been quite a disappointment for me. Please revert the commit.

Regards,
