Accidental screenshot file committed in public/ folder

[Akshak12]

Description
A screenshot file (Screenshot 2026-05-18 193128.png) has been accidentally
committed into the public/ folder by a contributor while adding the
CONTRIBUTING.md file.

This file is unrelated to the project and should not be part of the repository
as it:

• Unnecessarily increases the repository size
• Clutters the public/ directory which should only contain static assets
  and PWA-related files
• Gets included in the production build/ output, affecting app performance

Proposed Fix

• Delete Screenshot 2026-05-18 193128.png from the public/ folder
• No other changes required
