Found by running the unattended install in an offline QEMU VM:
- compgen is missing from nixpkgs' non-interactive bash (the package
shebang) — replaced with plain glob tests in hardware-db and prewipe
- disko's eval resolves <nixpkgs> via NIX_PATH (a dead channel on the
ISO) and tried channels.nixos.org — export NIX_PATH to the pinned
nixpkgs source and point the flake registry at an empty baked file
- lock nomarchy by path (the source the ISO carries) instead of
git+https: git inputs clone even when narHash is known, which kills
offline installs; `original` keeps the forge URL so a later
`nix flake update` re-resolves normally. Works from dirty-tree ISOs too.

- LUKS2 is the installer default; in exchange the generated config sets
the new nomarchy.system.greeter.autoLogin (greetd initial_session) —
the disk passphrase already gates the machine.
- @snapshots subvolume + nomarchy.system.snapper.enable: hourly/daily
timeline snapshots of / and the nixos-rebuild-snap helper, ported from
the previous iteration (3bdfc35), guarded to no-op on non-BTRFS roots.
- @swap subvolume with a swapfile sized to RAM by default (disko
mkswapfile handles NOCOW); the installer computes the resume offset
and wires boot.resumeDevice + resume_offset for hibernation.

Ported from the previous iteration's installer (3bdfc35), adapted to the
mkFlake world. gum TUI: disk pick, optional LUKS2, user/hostname/timezone,
DMI → nixos-hardware autodetection (hardware-db.sh). disko partitions
GPT + 1 GiB ESP + BTRFS subvolumes; the generated machine flake lands at
~user/.nomarchy (one mkFlake call, /etc/nixos symlinks to it) and
nixos-install makes it bootable (UEFI/systemd-boot, v1 single disk).
Offline by construction: the target flake.lock is composed from the rev
the ISO was built from (compose-lock.py), `nix flake archive` seeds the
target store, and the ISO pre-builds the template system + desktop.
First boot lands themed: the HM generation is pre-activated in chroot.
mkFlake grows two things for this: hardwareProfile now also takes a list
(autodetection emits several common-* modules), and installed systems get
the standalone home-manager CLI from the pinned input. Unattended mode
(NOMARCHY_UNATTENDED=1 + env) documented in docs/TESTING.md §4.
