Improve documentation of README

[Atharvverma1234]

The current README lacks visual references and a clear project structure,
which can be confusing for first-time contributors.

This issue proposes improving the README by:

• Adding UI screenshots
• Adding a clear project structure section
• Getting started

These changes will help new contributors understand the project faster
and improve overall onboarding.
