The foundation is in place to add Ubuntu website management tools in src/ubuntu-website-tools.ts. Future enhancements will include:

Web server control (Apache/Nginx)
System package updates
Website deployment with backup
SSL certificate management (Let's Encrypt)
Server performance monitoring
Website backup functionality
WordPress management
Firewall (UFW) management

Store SSH private keys securely
Use key-based authentication when possible
Limit SSH access to specific IP addresses
Keep your server updated
Use strong passwords or passphrases
Consider setting up environment variables in a .env file for sensitive information
