feat: Add monitoring points P1-P5 (installation outcomes, website events, API health)

- Create 3 Neon tables: installation_outcomes, website_events, api_health_logs
- Add API endpoints: track-installation-outcome, track-website-events, health-check
- Track CLI installation success/failure with timing and error classification
- Add website event tracker (search, cart, component views) with batched sendBeacon
- Add health-check cron every 15min with Discord alerts on failure
- Integrate tracking in all 6 installIndividual* functions with batchId support
