# Copies the native Baileys WhatsApp adapter, its whatsapp-auth and groups
# setup steps in from the `channels` branch; appends the self-registration
# import; registers `groups` and `whatsapp-auth` entries in the setup STEPS
# map; installs the pinned @whiskeysockets/baileys + qrcode + pino packages;
# builds. All steps are safe to re-run. QR/pairing-code authentication
# stays in the skill — this script only handles the deterministic install.
