Implement rich NixOS configuration system

✅ COMPLETE: Full NixOS-style configuration system implemented

🎯 Features:
- Rich configuration options for Quickshell, Hyprland, and Terminal
- Type-safe NixOS module options with defaults and descriptions
- Generated configuration files from Nix expressions
- Example configurations (gaming, productivity, minimalist)
- Comprehensive documentation

🔧 Configuration Modules:
- modules/components/quickshell-config.nix - Quickshell options
- modules/components/hyprland-config.nix - Hyprland options
- modules/components/terminal-config.nix - Terminal options

📝 Example Usage:
programs.dots-hyprland = {
  quickshell.bar.utilButtons.showColorPicker = true;
  hyprland.general.gapsIn = 6;
  terminal.colors.alpha = 0.90;
};

🎨 Generated Files:
- ~/.config/quickshell/ii/modules/common/Config.qml (NixOS-managed)
- ~/.config/hypr/general.conf (NixOS-managed)
- ~/.config/foot/foot.ini (NixOS-managed)

✅ Tested: All configurations build and activate successfully
🎉 Ready for production use with full NixOS declarative configuration!
