show_setup_config_menu was an Omarchy holdover where users edited
mutable config files at runtime. In Nomarchy:
- hyprland.conf, hypridle.conf, hyprsunset.conf, walker/config.toml,
waybar/config.jsonc are all Home-Manager-generated from declarative
settings — a `home-manager switch` clobbers any edit.
- hyprlock.conf and swayosd/config.toml point at paths the modules
don't deploy at all; open_in_editor created empty files.
- ~/.XCompose is a HM symlink into /nix/store — read-only.
Dropped the entire submenu function and the " Config" item from
show_setup_menu (and the matching *Config*) case branch). Persistent
settings go through the relevant nomarchy.* option in
/etc/nixos/home.nix (or system.nix); when the nomarchy.overrides.*
loader ships, a successor menu can route through
~/.config/nomarchy/overrides/.
Side effect (caught by the SCRIPTS.md regen): nomarchy-restart-xcompose
is now `unused?` — its only caller was the XCompose case I just
removed. Left for a future Pillar 3 cleanup rather than widening
this PR.
`bash -n` clean.
