Aggregates the loose OneCLI install, secret registration, and first-agent
wiring commands from /setup into three new dispatcher steps. Adds
--cli-only mode to init-first-agent so /new-setup can reach a working
2-way CLI chat with the bare minimum.
- setup/onecli.ts: idempotent install + PATH + api-host + .env, polls /health
- setup/auth.ts: --check verifies secret; --create --value registers it
- setup/cli-agent.ts: wraps init-first-agent --cli-only
- scripts/init-first-agent.ts: --cli-only mode; DM mode unchanged
