QualityHub: det nye private repo faar sit eget navn

Michaels beslutning: det private repo hedder Curabis/QualityHub.
Fordele: ingen omdoebnings-dans med den gamle fork (frisk repo, frisk
navn), og QualityHub er brandbart som CURABIS-produkt - det er ikke
laengere bare en BCQuality-fork, det er hjemstedet for hele
kvalitetsapparatet (regler + agenter + setup + governance).

Navneskel: repoet og kanal-klonen hedder QualityHub
(%USERPROFILE%\.claude\QualityHub); STANDARDEN indeni hedder fortsat
BCQuality (Microsofts tre-lags koncept, som 40+ regelfiler og alle
agenter refererer). Kun infrastruktur-referencer er skiftet:
git-URL'er og klon-stier i sync, onboarding, setup v19, maskin-
CLAUDE.md, CONSUMPTION, agent-fallbacks og Francis' felt-routing.
