token helper: render auth link as a scannable QR PNG

get-token.ts now writes the Remote Auth URL as a 512x512 QR image
(/tmp/javis_qr.png, override via QR_OUT) in addition to printing the link, so
it can be sent to the user and scanned from a second screen with the Discord
mobile app. Adds the qrcode dependency.
