- Email subject now follows spec format: PhaseFlow: [STATUS] - Day [cycleDay] ([phase])
- Daily email includes seed switch alert on day 15 (using getSeedSwitchAlert)
- Data panel HRV status now color-coded: green=Balanced, red=Unbalanced, gray=Unknown
- Data panel shows progress bar for week intensity vs phase limit with color thresholds

Implement email logging per observability spec:
- Add structured logging for email sent (info level) and failed (error level)
- Include userId, type, and recipient fields in log events

Add comprehensive metrics collection for production monitoring:
- src/lib/metrics.ts: prom-client based metrics library with custom counters,
gauges, and histograms for Garmin sync, email, and decision engine
- GET /api/metrics: Prometheus-format endpoint for scraping
- Integration into garmin-sync cron: sync duration, success/failure counts,
active users gauge
- Integration into email.ts: daily and warning email counters
- Integration into decision-engine.ts: decision type counters
Custom metrics implemented:
- phaseflow_garmin_sync_total (counter with status label)
- phaseflow_garmin_sync_duration_seconds (histogram)
- phaseflow_email_sent_total (counter with type label)
- phaseflow_decision_engine_calls_total (counter with decision label)
- phaseflow_active_users (gauge)
33 new tests (18 library + 15 route), bringing total to 586 tests.

Add email warnings for Garmin token expiration at 14-day and 7-day thresholds.
When the garmin-sync cron job runs, it now checks each user's token expiry and
sends a warning email at exactly 14 days and 7 days before expiration.
Changes:
- Add sendTokenExpirationWarning() to email.ts with differentiated subject
lines and urgency levels for 14-day vs 7-day warnings
- Integrate warning logic into garmin-sync cron route using daysUntilExpiry()
- Track warnings sent in sync response with new warningsSent counter
- Add 20 new tests (10 for email function, 10 for sync integration)
Test count: 517 → 537
