Bendik Aagaard LynghaugandClaude Fable 5 ce1ec9e4a9 rebrand: buuh — a friendly public fork under the uhhm org
Packages renamed to the @uhhm scope (@uhhm/buuh, @uhhm/buuh-html,
@uhhm/buuh-component, @uhhm/buuh-devtools, @uhhm/buuh-migrate,
@uhhm/bankai). Scoping is load-bearing twice over: npm routes registries
per scope so @uhhm/* resolves against project.uhhm.no while everything
else stays on npmjs, and it means this fork never squats upstream's
names anywhere. The codemod now migrates choo v7 apps to the @uhhm
names. README rewritten with the fork framing and full upstream credit;
the choojs RFC moves to docs/upstream-rfc-draft.md, in the drawer for if
this work ever goes home. API unchanged — choo() is still choo().

Also: Gitea Actions CI + release workflows (npm publish to the uhhm
registry on tag push, CDN bundle uploaded as a generic package),
npm run bundle producing dist-cdn/buuh.js (the whole framework as one
minified ES module for import-map use), docs/publishing.md explaining
what Gitea Packages is (a real npm registry) and is not (a CDN — serve
the bundle from a static host with module-safe MIME instead), and
onload.js constructing window.MutationObserver to match its own guard
(surfaced by smoke-testing the bundle outside a full browser).
