feat(archsetup): add Hyprland/Wayland desktop environment support

- Add DESKTOP_ENV config variable (dwm/hyprland/none, default: hyprland)
- Create wayland() and hyprland() installation functions
- Add display_server/window_manager conditional step wrappers
- Create dotfiles/hyprland/ with full config suite:
  - hyprland.conf with keybindings translated from DWM + sxhkd
  - waybar config matching conky status bar
  - hypridle/hyprlock for screen locking
  - wofi config matching rofi theme
  - gammastep config for Wayland (replaces redshift)
- Add Hyprland validation tests to validation.sh
- Update archsetup.conf.example with DESKTOP_ENV option
