Replace GNOME with Hyprland using JaKooLit's NixOS-Hyprland configuration

[Copilot]

This PR completely replaces the GNOME desktop environment with Hyprland window manager, implementing a modern Wayland-native tiling window manager setup based on @JaKooLit/NixOS-Hyprland configuration structure.

🔄 Major Changes

Desktop Environment Migration

• Removed: GNOME desktop environment, GDM display manager, X11 server configuration
• Added: Hyprland window manager with greetd/tuigreet login manager
• Migrated: From X11/Wayland hybrid to pure Wayland setup

Configuration Structure Overhaul

• Before: Monolithic configuration.nix file
• After: Modular host-based structure following JaKooLit's approach:

  hosts/BlitzWing/
  ├── config.nix          # Main system configuration
  ├── packages-fonts.nix  # Packages and fonts
  ├── users.nix          # User configuration
  ├── variables.nix      # Host-specific variables
  └── hardware.nix       # Hardware configuration
  

Package Ecosystem

Added comprehensive Hyprland ecosystem packages:

• Window Manager: hyprland, hyprlock, hypridle
• Status Bar: waybar with experimental features
• Utilities: grim, slurp, swappy, cliphist, wl-clipboard
• Launchers: rofi-wayland, wofi
• Terminal: kitty as default
• Notifications: swaynotificationcenter
• Wallpapers: swww for dynamic wallpaper management

🎨 User Experience

Preserved Features

• All existing applications and user packages maintained
• GTK theming (Gruvbox dark) preserved and enhanced
• Firefox configuration with gnome-theme support retained
