Read blueprint/20-entrevista.md, section 2, and ask questions 5 to 9 in that order: catalog,
price range, availability, escalation words, and internal channel.
One at a time. If .wca-estado.json already has an answer, show it and ask whether it changes.
Do not ask for it again from scratch.
All five come from the head of whoever installs it: here no one else's console is opened and no
credential is touched. The provider and the keys are Q10 to Q12, and they are done by /conectar.
When finished, write the answers in .wca-estado.json and close by saying what the closer does
now and what it still needs before it runs /conectar.
