feat: upgrade to production-grade systemd services
✅ Production SystemD Services Upgrade - Upgraded existing services instead of creating new ones - Added production-grade configuration with resource limits - Implemented real database persistence and logging - Added production monitoring and health checks ✅ Upgraded Services - aitbc-blockchain-node.service: Production blockchain with persistence - aitbc-marketplace.service: Production marketplace with real data - aitbc-gpu.service: Production GPU marketplace - aitbc-production-monitor.service: Production monitoring ✅ Production Features - Real database persistence (JSON files in /opt/aitbc/production/data/) - Production logging to /opt/aitbc/production/logs/ - Resource limits (memory, CPU, file handles) - Security hardening (NoNewPrivileges, ProtectSystem) - Automatic restart and recovery - Multi-node deployment (aitbc + aitbc1) ✅ Service Endpoints - aitbc (localhost): Marketplace (8002), GPU Marketplace (8003) - aitbc1 (remote): Marketplace (8004), GPU Marketplace (8005) ✅ Monitoring - SystemD journal integration - Production logs and metrics - Health check endpoints - Resource utilization monitoring 🚀 AITBC now running production-grade systemd services! Real persistence, monitoring, and multi-node deployment operational.
