Usage: deploy.sh

EINFACHES DEPLOYMENT:
  - Erkennt automatisch installierte Scripts in ~/bin
  - Einfache Auswahl mit bash select
  - Einfache Server-Auswahl (web, mx, logger, support)
  - Optional: bashrc deployment

FEATURES:
  - Auto-Detection von Scripts in ~/bin
  - Symlink-basiertes Deployment
  - PATH-Setup für target servers
  - Dry-run verfügbar

ENVIRONMENT:
  LUSER         Required: Username für SSH-Verbindungen
