When a coding agent does the work but leaves no trace of co-authorship, that
change used to land with no human attached to it. A real, merged PR that no one
was credited for.

Starting today, Mesmer runs post-attribution. When agent-authored work carries
no co-author, we assign the responsible human by walking a fallback chain until
someone is found.

### How the fallback chain works

Credit goes to the first role present, in order:

- **Opener** — whoever opened the pull request.
- **Assignee** — the assigned owner, when there's no opener to credit.
- **Merger** — whoever merged the change.
- **Approver** — the reviewer who approved it.
