Move AUR/local deps to optdepends, deploy swaync via install hook

AUR packages can't be resolved by pacman when moonarch-git is
installed from the Gitea Package Registry. Move them to optdepends
since they're managed separately via packages/aur.txt.

swaync config files conflict with the swaync system package —
deploy via .install hook like foot and waybar configs.
