Better F3 Reborn

# Changelog v2.1.1

This update focuses on user customization and HUD positioning to ensure compatibility with other mods and individual preferences.

### ✨ New Features
* **Dynamic Background Toggle:** Added **F3 + J** to toggle the dark background boxes behind text modules on/off at runtime.
* **Compass Positioning:** The vertical position of the compass can now be manually adjusted via the `compassYOffset` setting in the config.
* **Hex-Color Support:** Background colors can now be fully customized using Hex-Strings (e.g., `0x000000` for black) in the config file.

### 🔧 Improvements & Fixes
* **Optimized Default HUD:** Re-adjusted the default compass position to sit perfectly above the standard Minecraft hotbar/health-bar.
* **Persistent Compass Design:** The compass background now stays active regardless of the F3+J setting to maintain maximum readability.
* **GPU Info Cleanup:** Further refined system information strings for Linux/Mesa users (especially for Ryzen APUs).
* **Code Refactor:** Moved background rendering to a centralized utility class for better performance.

### ⚠️ Installation Note
**IMPORTANT:** Please delete your old configuration file (`config/betterf3reborn.cfg`) before launching the game with this update. This ensures that the new configuration entries (like the Y-Offset and Hex-Colors) are generated correctly.
