Mod: - %config slots/pull/publish/unpublish for the four cloud slots - %showcase [new|popular] [page] | load | copy, with number references - %cloud opens a CloudScreen (link/unlink, slots, showcase) on vanilla widgets - %config load IDDQD works offline (everything off except ChinaHat) - default backend URL is now the production gateway - shared ConfigRemoteApplier and ClientThread replace per-class copies - %link unlink revokes the link on the server, then clears the local token Backend: - POST /device/revoke (RFC 7009 style self-revoke, always 204), rate limited to 10/min per IP at the gateway CloudScreen is compiled but has not been opened in a running client yet.
