How it works

• Commander wires subcommands, options, and help output.
• Chalk colors messages; defaults to plain text if color missing.
• Inquirer powers interactive flows (intro, json, init).
• File utilities use Node’s fs/path; hashing uses crypto.

Dependencies

• commander - Command-line interface framework
• chalk - Terminal string styling
• inquirer - Interactive command-line prompts
