I added a button for browsing detected Wi-Fi networks.

The ESP32-S2 Mini built-in BOOT button is used as the navigation button.

I also added button debounce to prevent multiple inputs from a single press. I improved the project structure and documentation.

Changes:

• Added GitHub repository structure
• Added README
• Added MIT license
• Improved code comments
• Added hardware documentation

The project is now easier for others to build.
