feat(root): add Modugen template configuration to install script

This change adds automatic configuration of Matugen templates for Modus themes, ensuring a consistent look‑and‑feel across Hyprland and terminal setups. It introduces checks to prevent duplicate entries and provides user feedback via progress and success messages.

- New Features:
  - Added Modus template blocks for Matugen (modus and hyprland)
  - Integrated progress and success messaging for template installation
- Enhancements:
  - Updated Hyprland Lua path to an absolute location
  - Added validation for existing Matugen config file
- Bug Fixes:
  - None
