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.
bot/src/get-token.ts uses discord.js-selfbot-v13 DiscordAuthWebsocket: it
prints the Discord Remote Auth URL (https://discord.com/ra/<code> — the same
thing a login QR encodes). Open it on a phone with the Discord app, approve the
"New login" prompt, and the user token is written to .env as
DISCORD_SELFBOT_TOKEN. Works from a single mobile device (no second screen, no
password, no browser devtools). `bun run token`.
