cc-architect (plugin standards authority, v1.0.1) now lives here with the
other universal system plugins, registered in the marketplace manifest and
installed via the standard local-plugins symlink.
Also sync the os-backlog marketplace description to its updated
plugin.json so the cross-repo acceptance gate passes; that rewrite is
otherwise untouched here.
