8FF - SEO Agency Automation Suite | ⏰ Schedule + Audit Intake

### 🚀 How It Works
- **Audit Intake**: Webhook at /audit-intake → validate → enrich (weather + rankings) → route by urgency → Slack + respond.
- **Digest**: Weekly schedule → fetch rankings from Cockpit → batch → check live positions → aggregate → post to Slack.
- **Report**: Monthly schedule → fetch rankings → aggregate by site → generate insights → post to Slack.
- **KPI Blast**: Daily schedule → fetch KPI API → compare to targets → Slack alert + log to Cockpit.

All errors are caught and routed to `#errors` Slack channel.
