Implement final version of Weather App

[Ki0taka]

🌦 Backend Challenge #1 – Weather API CLI App

Implementation of the Weather CLI:

• Added index.js with async/await-based logic to fetch weather data from the OpenWeatherMap API, handle errors, and display formatted output for city, temperature, weather condition, humidity, and wind speed.

Environment and dependency setup:

• Added .env and node_modules/ to .gitignore to prevent sensitive information and dependencies from being committed.
• Created package.json specifying project metadata, dependencies (dotenv, node-fetch), and script for running the CLI.
• Added package-lock.json to lock dependency versions for reproducibility.

Documentation:

• Added a comprehensive README.md describing features, usage instructions, error handling scenarios, project structure, and dependencies.
