Add README.md badges (WIP)

[callogan]

Add informative badges to README.md

🐞 Problem
The project’s README.md currently lacks informative badges that help quickly communicate important project status indicators (like build status, license, and contributor activity).

🎯 Goal
To improve project visibility, transparency, and contributor friendliness by adding relevant badges to README.md.

💡 Possible solutions
Add a set of badges (via shields.io) at the top of README.md, including:

• GitHub Workflow Status;
• License;
• Contributors count;
• Last commit.

📋 Steps to solve the problem

1. Identify existing GitHub Actions workflows and generate the badge URL for build status.
2. Add a license badge reflecting the project’s license.
3. Add a badge for the last commit date and contributors.
4. Place all badges at the very top of README.md for easy visibility.
5. Create a pull request with a clear description and screenshots of the updated README.md preview.
