The advisor-watchdog.md slash-command table described /advisor,
/advisor on, and /advisor off as toggling the persisted advisor.enabled
setting. Commit 3c5e32f21b made the toggle session-local: setAdvisorEnabled
mutates only the in-memory #advisorEnabled field and writes nothing to
config.yml. Corrected the three rows to describe the session-scoped
override.
