- Skip redundant notifyListeners in HiddenLibrariesProvider init when set is empty (empty→empty is a no-op for consumers) - Track last-seen hidden keys in DiscoverScreen to avoid reloading content when the listener fires without an actual change - Track previous online server set in MultiServerProvider; only re-check DVR availability when a new server comes online - Remove dead content-loading pipeline from libraries_screen (sorts, pagination, filters, items) that was never rendered - Move /media/providers fetch into PlexClient.create() init, replacing lazy EPG cache and providing libraries including shared items
