Examples:
  $ nopy                      Interactive cube selection and deployment
  $ nopy -R                   Repeat the last deployment session
  $ nopy -H <id>              Run a specific session from history
  $ nopy -l session.json      Load and replay a saved session file
  $ nopy -s session.json      Save session to file after deployment
  $ nopy -n                   Dry run (show plan without executing)
  $ nopy -P                   Print deploy commands only
  $ nopy history              List all saved sessions
  $ nopy clear-history        Clear session history

Session Replay:
  Sessions are automatically saved to history after each deployment.
  Use 'nopy history' to see available sessions and their IDs.
  Use 'nopy -R' to quickly repeat the last session.
  Use 'nopy -H <id>' to run any session from history.
