Subject: [PATCH 1/5] UI Enhancement: Add Theme Toggle with Light Mode Support
 for Better Visualization #29

- Improved light mode visibility for all hero/feature/tool texts and cards
- Applied zinc gradient to hero heading in light mode
- Split hero heading into two lines for readability
- Fixed alignment issues in hero section
- Made 'Client-Side Processing' and icon black in light mode
- Used reliable CSS/Tailwind for theme-based color switching
- Cleaned up Hero.jsx, removed unwanted code

Closes #29
