Zero data retention

We log invocation count + channel name for ops. No prompt text, no answers, no PII stored beyond the slash log.

Why this exists

1. Slack is the cost UI for half the org. Engineers, PMs, and finance live there — your dashboard doesn't.
2. 2-second answers beat 2-minute dashboards. The bot returns the same 3-bullet root-cause analysis you'd get from the Anomaly Autopsy engine.
3. Audit-friendly. Every query is logged with channel + user so finance can prove "we asked, we acted".
