Bernardo Magri 1f22e996dc feat: nomarchy.lib.mkFlake — one-call downstream wrapper + hardware profiles
Downstream users now own only system.nix and home.nix; their flake.nix is
generated once from the template and never hand-edited. mkFlake (lib.nix)
wires both layers and maps hardwareProfile = "<name>" to nixos-hardware
modules (new input, pinned here, nixpkgs follows ours; unknown names fail
with did-you-mean suggestions). Flake checks evaluate the template through
mkFlake — including a real profile — so drift fails `nix flake check`.

Also from the live-VM testing session: install the home-manager CLI in the
live ISO and pin flake inputs transitively (offline theme switching needs
stylix's own inputs too), plus swww→awww doc updates.

# My Nomarchy machine
1. Overwrite the placeholder hardware config with the real one:
`nixos-generate-config --show-hardware-config > hardware-configuration.nix`
2. Set `flake.nix` up **once** (Nomarchy repo URL, your username, optionally
a `hardwareProfile` from <https://github.com/NixOS/nixos-hardware> — an
unknown name fails the rebuild with suggestions). After that the flake is
never touched again: your machine lives in `system.nix` (hostname,
services — the login user is created from `username` automatically) and
`home.nix` (your packages).
3. `git init && git add -A` — flakes only see tracked files, including
`theme-state.json`.
4. System: `sudo nixos-rebuild switch --flake .#default`
5. Desktop: `nix run home-manager -- switch --flake .#me`
(afterwards just `home-manager switch --flake .#me` — it's installed)
6. Clone/symlink this directory to `~/.nomarchy` (or export
`NOMARCHY_PATH`) so `nomarchy-theme-sync` knows where the state lives.
Day-to-day:
```sh
nomarchy-theme-sync list # 21 shipped presets
nomarchy-theme-sync apply gruvbox # writes state + home-manager switch
nomarchy-theme-sync bg next # cycle wallpapers (instant, no rebuild)
```
The system layer only needs `nixos-rebuild` when you change `system.nix`.
