// DOMINUS — PM2 ecosystem file for process management.
//
// Usage:
//   pm2 start ecosystem.config.cjs
//   pm2 save                           # persist the process list
//   pm2 startup                        # auto-start on boot
//
// For a multi-instance cluster (recommended for production):
//   pm2 start ecosystem.config.cjs -i max
