🎉 Complete Nomad monitoring infrastructure project

✅ Major Achievements:
- Deployed complete observability stack (Prometheus + Loki + Grafana)
- Established rapid troubleshooting capabilities (3-step process)
- Created heatmap dashboard for log correlation analysis
- Unified logging system (systemd-journald across all nodes)
- Configured API access with Service Account tokens

🧹 Project Cleanup:
- Intelligent cleanup based on Git modification frequency
- Organized files into proper directory structure
- Removed deprecated webhook deployment scripts
- Eliminated 70+ temporary/test files (43% reduction)

📊 Infrastructure Status:
- Prometheus: 13 nodes monitored
- Loki: 12 nodes logging
- Grafana: Heatmap dashboard + API access
- Promtail: Deployed to 12/13 nodes

🚀 Ready for Terraform transition (静默一周后切换)

Project Status: COMPLETED ✅
