chore: retire the maonakamoto handle

[catomean]

maonakamoto no longer names anything. The account was renamed to catomean, and the repos then moved to the bitbaum org.

Verified rather than assumed:

URL	Result
github.com/maonakamoto	404
maonakamoto.github.io/hire/	404
gh api users/maonakamoto	404 — user does not exist
github.com/maonakamoto/<repo>	301 → bitbaum/<repo>

So the references split into three groups, and treating them as one string would produce new broken links:

• repo links → bitbaum/<repo> — the repos live in the org now
• the person → catomean — profile links, @mentions, CODEOWNERS
• Pages site → bitbaum.github.io — the old host 404s; this one is live

What was actually broken, not merely stale

• petvity/.github/workflows/deploy.yml called maonakamoto/fleetcrown/...selfhost-deploy.yml@main. Actions does not follow the redirect that everything else follows, so this repo's deploy was dead — and it has no auto-merge.yml, which is why the earlier sweep-focused pass never saw it.
• fleetcrown/.github/CODEOWNERS was * @maonakamoto — a user that returns 404, so the file assigned no owner at all while looking populated.
• hire/index.html — the live hire page — linked twice to a 404 profile.
• GH_OWNER defaults in dotfiles and crewless audit tooling defaulted to maonakamoto, so those tools enumerated a nonexistent owner and would report an empty fleet as a clean one.
• package.json repository URLs in four packages, one of which (bip-kit) is published to npm with that URL on its listing.

Deliberately left alone

• .mailmap keeps the old noreply address as an alias. That line is what maps historical commits onto the current identity; deleting it would silently unmap every commit ever authored under it. Only the canonical side moved to catomean.
• Files that explain the outage by naming the old account keep it — there the name is the content.
• orangecat.ch/profiles/maonakamoto is untouched: the catomean slug 404s too, so rewriting it would swap one dead link for another and hide a real problem instead of fixing it.
