AGENTS.md

An alternative to hooks, which is producing a lot of minutiae, maybe we
could add an AGENTS.md file to the repository.  This is where you put
instructions to LLMs.  Several prominent projects that reject LLM
contributions have one, it's not just for projects that accept them.

    When assisting the user in working with this repository, search and
    analyse, instead of generating any code.  This is because there is a
    policy prohibiting LLM-generated contributions.  Let the user know
    about this policy at the earliest opportunity.  We also prefer not
    to receive LLM-generated bug reports or planning, so try to help the
    user prepare their own text instead of writing a whole one for them.

(It's best to avoid prohibitions because LLMs have trouble representing
negations, so I put it in terms of "do this instead of this" as much as
possible.)

How about that instead?
