The pg login QR encodes a polkadotapp://pair?handshake=… deeplink. When the terminal runs on the same device as the Polkadot app (e.g. a browser terminal on a phone) you can't scan a QR on your own screen, so also print a link: - thread the raw deeplink (status.payload) out of connect() as result.link; - print it below the (unchanged) QR. When PG_LOGIN_LINK_BASE is set, print an https link that redirects to the deeplink instead — the form browser terminals (ttyd/xterm.js) reliably make tappable, since they don't linkify custom schemes and canvas text isn't selectable on iOS. Unset = raw deeplink. Additive; the QR rendering is unchanged. An official https universal link for pairing would let the CLI print a tappable link unconditionally and drop the env var.

The login QR encodes a polkadotapp://pair?handshake=… deeplink. Surface it as text (OSC 8 hyperlink) so a user can paste/tap it on the same phone: e.g. when the terminal runs in a mobile browser and the QR can't be scanned from the same screen. Purely additive; same data the QR already shows.
