✅ Modern UI – Features a colorful ASCII banner and stylish prompts using figlet and chalk.
✅ Real-time API Calls – Uses axios for seamless communication with Gemini 2.0 Flash.
✅ Command Line Flags – Includes useful commands:

• --help → Show available commands
• --version → Show the current version
• --model → Display the current Gemini model
• --remove-api → Remove the stored API key
• --update → Update shellmancer to the latest version

🌐 API Integration

This CLI interacts with the Gemini API using the following endpoint:

https://generativelanguage.googleapis.com/v1/models/gemini-2.0-flash:generateContent?key=YOUR_API_KEY

The API expects a JSON payload structured like this:

{
  "contents": [
    {
      "parts": [
        { "text": "Your query goes here" }
      ]
    }
  ]
}

The API key is dynamically inserted into the URL at runtime.
