Create a README badge for each track showing problem count

[AshayK003]

Background

The main README.md lists 4 tracks with problem counts but uses static text. Dynamic badges would make the repo look more professional on GitHub.

Task

Create shields.io badges for each track that auto-display the problem count:

1. Count .md files in each track directory:

   • global-south-impact/ → 10 files
   • us-civic-tech/ → 10 files
   • india-impact/ → 5 files
   • rapid-prototype/ → 11 files

2. Add shields.io dynamic JSON badges to README.md using the GitHub API to count files

3. Example: https://img.shields.io/badge/dynamic/json?label=Global%20South&query=...&url=...

Hints

• Use GitHub's tree API to count files: https://api.github.com/repos/AshayK003/hackathon-problem-statements/git/trees/master?recursive=1
• shields.io supports the dynamic badge type

Expected output

A single PR updating README.md with 4 new badges inline with existing ones.

Skills needed

• Markdown
• Basic JSON/URL construction

Estimated effort: 1 hour
