Package Manager Setup for Cursor

Usage:
  node scripts/setup-package-manager.js [options] [package-manager]

Options:
  --detect        Detect and show current package manager
  --global <pm>   Set global preference (saves to ~/.cursor/package-manager.json)
  --project <pm>  Set project preference (saves to .cursor/package-manager.json)
  --list          List available package managers
  --help          Show this help message

Package Managers:
  npm             Node Package Manager (default with Node.js)
  pnpm            Fast, disk space efficient package manager
  yarn            Classic Yarn package manager
  bun             All-in-one JavaScript runtime & toolkit

Examples:
  # Detect current package manager
  node scripts/setup-package-manager.js --detect

  # Set pnpm as global preference
  node scripts/setup-package-manager.js --global pnpm

  # Set bun for current project
  node scripts/setup-package-manager.js --project bun

  # List available package managers
  node scripts/setup-package-manager.js --list
