After cli-agent, prompt the user to connect a messaging app. For now
only Telegram is offered; "skip" falls through to the existing CLI
flow.
setup/add-telegram.sh runs the scriptable half of /add-telegram: fetch
the channels branch, copy the adapter + pair-telegram files, append
the self-registration import, install @chat-adapter/telegram@4.26.0
(pinned to match the skill), rebuild, collect TELEGRAM_BOT_TOKEN via
silent paste, write .env + data/env/env, and kick the service so the
new adapter is live. Idempotent throughout.
setup:auto then runs the existing `pair-telegram` step with
--intent main. The step emits the 4-digit code in its status stream,
which is already forwarded to stdout by runStep.
