git-auto-rebase-cli v1.1.1

Usage:
  git-auto-rebase [command]

Commands:
  rebase        Automatically rebase current branch onto main (default)
  amend         Amend last commit and force push with --force-with-lease
  amend-push    Same as amend
  --help, -h    Show this help message

Examples:
  git-auto-rebase           # Run auto rebase (default)
  git-auto-rebase rebase    # Run auto rebase explicitly
  git-auto-rebase amend     # Amend last commit and push
  git-auto-rebase --help    # Show this help

Safety Features:
  - Prevents amend/push operations on main branch
  - Uses --force-with-lease for safer force pushes
  - Checks for clean working directory before rebase
  - Comprehensive error handling
