feat(themes): declaratively manage icons, cursors, and dark/light modes

- Automatically detect light mode via 'light.mode' file in theme folder
- Read icon theme name from 'icons.theme' file in theme folder
- Switch Stylix polarity and iconTheme based on theme selection
- Add yaru-theme and bibata-cursors to default packages
- Remove obsolete imperative nomarchy-theme-set-gnome script

 1.  **Repo Detection:** Identifies the location of the Nomarchy source.

 3.  **User Files:** Generates skeleton `system.nix` and `home.nix` files for the user to customize.
-4.  **Bundling:** Copies the entire Nomarchy source to `/etc/nixos/nomarchy` so the system can be rebuilt offline.
+4.  **Flake Updates:** Uses the public Git repository as the upstream source, allowing users to update their system via `nix flake update`.
 
 ### 3. Home Manager Integration
 * **Hybrid Declarative State:** While the distro is declarative, it uses state files in `~/.config/home-manager/` (managed by the distro's scripts) to allow for instant UI feedback (theming, fonts, wallpapers) without needing a full system rebuild for every small tweak.
