// BackOne DPI — Production SFTP Deployment Script (Windows Compatible)
//
// Usage: node scripts/deploy-sftp.js
// Requires: npm install ssh2-sftp-client ssh2 (already in devDependencies)
//
// This script:
//   1. Verifies the production build exists (.next/standalone)
//   2. Connects to server via SFTP (port 2222)
//   3. Uploads all required files to the remote server
//   4. Runs post-deploy commands via SSH (npm install, PM2 restart)
// ─────────────────────────────────────────────────────────────────────────────
