Phase 1 Week 2: Infrastructure & Monitoring

Added comprehensive production infrastructure:

Systemd Service:
- guruconnect.service with auto-restart, resource limits, security hardening
- setup-systemd.sh installation script

Prometheus Metrics:
- Added prometheus-client dependency
- Created metrics module tracking:
  - HTTP requests (count, latency)
  - Sessions (created, closed, active)
  - Connections (WebSocket, by type)
  - Errors (by type)
  - Database operations (count, latency)
  - Server uptime
- Added /metrics endpoint
- Background task for uptime updates

Monitoring Configuration:
- prometheus.yml with scrape configs for GuruConnect and node_exporter
- alerts.yml with alerting rules
- grafana-dashboard.json with 10 panels
- setup-monitoring.sh installation script

PostgreSQL Backups:
- backup-postgres.sh with gzip compression
- restore-postgres.sh with safety checks
- guruconnect-backup.service and .timer for automated daily backups
- Retention policy: 30 daily, 4 weekly, 6 monthly

Health Monitoring:
- health-monitor.sh checking HTTP, disk, memory, database, metrics
- guruconnect.logrotate for log rotation
- Email alerts on failures

Updated CHECKLIST_STATE.json to reflect Week 1 completion (77%) and Week 2 start.
Created PHASE1_WEEK2_INFRASTRUCTURE.md with comprehensive planning.

Ready for deployment and testing on RMM server.
