/**
 * PM2 Production Deployment Configuration
 *
 * PM2 is a Node.js process manager that:
 * - Automatically restarts crashed applications
 * - Manages application startup on system boot
 * - Provides centralized logging
 * - Enables zero-downtime reloads
 * - Monitors CPU, memory, and other metrics
 *
 * Installation: npm install -g pm2
 *
 * Usage:
 *   pm2 start ecosystem.config.js                    # Start all apps
 *   pm2 start ecosystem.config.js --only production  # Start specific app
 *   pm2 monit                                        # Monitor in real-time
 *   pm2 logs                                         # View logs
 *   pm2 restart production                           # Restart app
 *   pm2 delete production                            # Stop and delete app
 *   pm2 save                                         # Save PM2 config
 *   pm2 startup                                      # Enable auto-startup on boot
