fix(api): tell agents how a person connects their terminal

The CLI auth operations in the agent API catalog had bare summaries, so a
chat agent asked to connect a person's terminal could find the endpoints but
not who starts the flow, and spent its whole turn reading source code to find
the command. Describe the person-run paperclipai auth login flow, the browser
approval, whoami/logout, and that agents must not create or approve challenges,
hand out agent keys or ask for passwords.
