China region proposal replaces extra repository trust with Omarchy mirrors

xdanger's omacom/omarchy#13690 remained open at the October 19 check. On October 15, omarchybot reported pushing five commits and rewriting the description after extending the proposal on maintainer direction. The proposed World or China setting coordinates package mirrors and developer-tool registries for downloads that can be slow or unreachable in mainland China.

The revision removes the additional archlinuxcn repository and keyring, instead prioritizing Omarchy's China replicas of the same signed packages. omarchybot explained that the extra keyring would have widened package-signing trust. The switcher also gained rollback handling and preservation of user registry settings.

omarchybot reported testing a live China-to-World switch, package downloads and developer-tool registries on a fresh worker in omacom/omarchy#13690:issuecomment-6185224082. Those are contributor-reported results; the comment explicitly left the proposal waiting on the maintainer.
