Merging master's rename of the client manifest field left this package on the
old `dshClient` name. The row still composed and its empty node half still
activated, but the browser roster scan never matched it, so the whole settings
section vanished with no error anywhere.
verify-cordis-config now requires a packages/client package's "./client"
export and its dsh.client declaration to agree in both directions; the
composition file cannot tell a surface plugin from a Host plugin, so the
manifests are where this is checkable. The check is scoped to that group
because a Host package's "./client" export is the typed wire face its browser
consumers import, not a plugin the roster serves.
