feat(hyprland): session Hyprland en test à côté d'i3

- Hyprland via UWSM (comme Omarchy), à choisir à la connexion ;
  i3 reste la session par défaut
- config Lua (format Hyprland >= 0.55) : raccourcis bépo d'i3,
  apparence Omarchy, Ghostty comme terminal
- waybar, hyprlock, swaybg, grim/slurp, wl-clipboard, brightnessctl
- workspace-run : support de hyprctl et des options en --opt=
- stt-dictate : wtype sous Wayland au lieu de xdotool
