Enhance README.md with more detailed documentation

[0xperp]

Closes #4

This PR enhances the README.md file to make it more informative and visually appealing. Changes include:

• Added a features section showcasing key capabilities of the application
• Improved formatting with emoji icons for better visual organization
• Created a table for command documentation for easier reference
• Added project structure information to help contributors understand the codebase
• Referenced the future CONTRIBUTING.md file (which is part of another PR)
• Better organized sections with consistent formatting

These improvements make the project more approachable for new users and provide clearer guidance for getting started with the application.
