Add special thanks section for Anna in README

[Copilot]

This PR adds a heartfelt acknowledgment section to the README expressing appreciation for Anna's contributions and support to the Dropped project.

Changes Made

Added a new "🙏 Special Thanks" section to README.md that:

• Expresses sincere gratitude to Anna for her support, encouragement, and inspiration
• Acknowledges her belief in the project and its impact
• Uses a warm, friendly tone consistent with the existing README style
• Includes an emoji (💙) to match the visual style of other sections

The new section is positioned prominently before the footer to ensure visibility while maintaining the overall flow of the document.

Example

## 🙏 Special Thanks

A huge thank you to **Anna** for all the incredible support, encouragement, and inspiration. Your contributions and belief in this project mean the world. We couldn't have done this without you! 💙

This addition enhances the README by recognizing the important people who make this project possible.
