A site allowed without "Remember" lives only in the background's in-memory connectedSites map. Settings never listed it, and AUTISTMASK_REMOVE_SITE, sent on every remove, did nothing, so the user could not end such a connection. Settings now asks the background for those sites and lists them under Connected Sites. Removing a site from Allowed Sites or Connected Sites drops its remembered entry under every address and sends AUTISTMASK_REMOVE_SITE with the hostname; the background deletes every matching connectedSites entry and sends accountsChanged with an empty list to the site's tabs. Only the extension's own pages may send either message. Model: opus-5-5
