Rename xmonad/ to jade/ and restructure as a complete desktop environment
with hybrid NixOS and home-manager modules. This establishes jade as a
self-contained, gruvbox-themed DE that can eventually be extracted as a flake.
Changes:
- Create jade/ with NixOS module (WM, system packages, GTK theme)
- Create jade/home.nix for home-manager services (wezterm, picom, dunst)
- Move dmenu with gruvbox patches into jade/dmenu/
- Convert wezterm to pure Lua config with gruvbox-material colors
- Move xinitrc into jade/ directory
- Remove feh/scrot from global env (now in jade)
- Remove dmenu overlay from global overlays
- Simplify home-manager desktop features to just user apps
This follows the pattern of real DEs (GNOME, KDE) where system and user
configs are split across NixOS and home-manager modules.
- Add direnv module with nix-direnv integration, replacing manual hook
- Disable starship's add_newline for more compact prompt
- Clean up comments across CLI features for better readability
Added the necessary configurations and dependencies to enable Flatpak in the Fuchsia module.
This includes enabling the xdg portal for default settings and adding the flatpak service.
