"""Тесты chatballs CLI (этап 1): deploy workflow ordering, validation, lock, doctor, status.


Запускают реальный bash-скрипт против замоканного docker/flock (см. conftest.py).

Покрывают: SPEC-CHATBALLS-0019 §11 (lock), §12 (doctor), §17 (deploy workflow),

§29 (observability). Не требуют Docker daemon.
