# Install the native WhatsApp (Baileys) adapter and its whatsapp-auth + groups
# setup steps. No credentials in env — WhatsApp uses linked-device auth, run
# by the whatsapp-auth step as a separate process. The adapter's factory
# returns null until store/auth/creds.json exists, so it's safe to install
# this before auth runs; the driver restarts the service *after* auth
# succeeds.
#
# Emits exactly one status block on stdout (ADD_WHATSAPP) at the end. All
# chatty progress messages go to stderr so setup:auto's raw-log capture sees
# the full story without cluttering the final block for the parser.
