"""One-shot client-activity monitor — read-only, never touches the bot or analytics.

  python tools/client_monitor.py <db> [--recent N]

Shows: query volume + sessions, the N most recent real questions (what the owner
or his customers actually typed), most-asked, unanswered questions (knowledge
gaps), captured leads, CSAT, and the last unhandled /chat error. Everything
comes from admin GET endpoints, so running this adds NOTHING to the client's
analytics (unlike a live probe).
