When `dev connect` runs with no credentials (no --robot-client-id/secret, no
--unified-app-id) in a real terminal, it now guides the user instead of failing:
- Ask "new app or existing app?".
- Existing: read a unified-app-id (reuses the credentials-get path) or an
explicit clientId/clientSecret pair.
- New: read the app name, robot display name and description, submit the async
robot-create task, then poll for the result to obtain credentials. This has a
real side effect (it provisions a real robot app).
connect_onboarding.go keeps the flow channel-agnostic and io-injected so the
whole decision tree is unit-tested with a mock runner and scripted stdin (no
network, no real provisioning). Non-interactive invocations — scripts, daemons,
pipes, and --dry-run — are unchanged: they still require an explicit credential
flag, so nothing that worked before starts prompting.
Tests cover: existing/unified, existing/raw-creds, new-app submit+poll (asserts
the submit_robot_create_task / query_robot_create_result calls and params),
invalid choice, and a missing required field (no side-effecting call).
Note: the real provisioning path shares the same unverified credential field
names as devAppFetchCredentials (clientId/appKey, clientSecret/appSecret — see
its TODO(verify)); the live create→credentials flow is to be verified on the
pre-prod gateway with the -dws-devapp prerelease before relying on it.
