Major improvements:
- ✅ Removed legacy setup.py, now using pyproject.toml
- ✅ Created comprehensive help system with `fab help`
- ✅ Dramatically simplified command structure:
  * setup.server (vs recipe-generic-server.setup-server)
  * db.psql.create-user (vs database.psql.db-psql-create-user)
  * security.secure-server (vs security.firewall.fw-secure-server)
- ✅ Organized database commands by type (db.psql.*, db.mysql.*)
- ✅ Fixed all linting issues (100-char lines, imports, code quality)
- ✅ Updated to use .venv virtual environment
- ✅ Added bootstrap.sh for automated setup
- ✅ Updated CLAUDE.md with modern patterns

Commands are now 50-70% shorter and much more intuitive\!

This commit fixes critical issues with SSH key installation and sudo authentication,
enabling full automation of secure server deployments.

Major fixes:
- Fix SSH key installation order in recipe_generic_server.py
- Fix Fabric sudo password handling via INVOKE_SUDO_PASSWORD environment variable
- Fix nginx.py use_sudo parameter error in file transfer operations
- Add proper validation functions for user and SSH configuration
- Add connection verification with working sudo tests

Security improvements:
- Ensure SSH keys installed before disabling root login
- Reconnect as admin user (not auto user) after root disable
- Add passwordless sudo option with security warnings
- Validate configuration early in deployment process

New features:
- Environment variable sudo authentication: export INVOKE_SUDO_PASSWORD=password
- Comprehensive connection verification after user creation
- Enhanced configuration validation with proper error messages
- Updated documentation with secure workflow examples

The complete workflow now works:
1. fab -H root@host recipe.gen-install --cfg-file=config (sets up secure server)
2. export INVOKE_SUDO_PASSWORD=admin_password
3. fab -H admin@host:port web.nginx.install (automated sudo commands work)
