The slug (plugin marketplace "triple-c-<slug>", plugin tree
"plugins/<slug>/") was built from the editable display name. After a
rename the next sync registered the new marketplace, skipped the plugin
install because the state's commit matched, then removed the old
marketplace: the plugin was gone while the report said nothing changed.
marketplace_slug now takes the id only ("mp-<id8>"). With plugin state
kept per slug (I1), containers synced with the old "<name>-<id8>" slugs
move over on their next sync: plugins are installed under the new name,
the old copies uninstalled and the old registration dropped. A sync
script test covers that migration (it fails on the pre-I1 script).
