Restructure dotfiles : suppression outils abandonnés, migration sway→hyprland, neomutt→aerc

- Supprimés : fish, qtile, X, vim, sway, neomutt (+ package systemd vide)
- Nouveau package hyprland : waybar, rofi, mako, gammastep, rofi-pass, systemd (mail+kanata+mpd+voxtype), script rofi
- Nouveau package aerc : config aerc + infra mail (msmtp, khard, vdirsyncer) migrée depuis neomutt
- Nettoyage .gitignore : suppression entrées neomutt/vim, ajout patterns moc/mpd/vifm manquants, vdirsyncer/status pour aerc
- Mise à jour des configs trackées modifiées (nvim, zsh, tmux, git, newsboat)
