Add a self-contained "Enabling hibernation on an existing machine (no
reinstall)" section to docs/MIGRATION.md, per the settled #76 call to
document migration rather than ship a tool. Covers: @swap subvolume
creation (subvolid=5), btrfs mkswapfile (NOCOW), reading the resume
offset via map-swapfile, and wiring fileSystems."/swap" + swapDevices +
resumeDevice + resume_offset into system.nix. Flags the /swap mount as
required on the hand-edit path (a fresh install inherits it from
disko-generated hardware-config). Notes the zram-priority reservation,
a no-LUKS variant, and the swap=0 opt-out.
Verification: V0. All read-only commands run live against this machine's
LUKS(cryptroot)+btrfs(@)+/swap/swapfile layout; nix flake check
--no-build green.

Installer: disko @snapshots → /.snapshots + first-boot nested
/home/.snapshots. Migration machines may use top-level
@home-snapshots (TuringMachine); either works for snapper.
Add docs/HARDWARE.md (layers, install path, firmware/fingerprint/NVIDIA
deep dives, unsupported machines, contributing a DMI line). Link from
README and MIGRATION; queue firmware UI, doctor checks, detect-hw CLI,
and related PROPOSED items in BACKLOG.
Bernardo asked whether TuringMachine (NixOS 25.11) could adopt Nomarchy
without a reinstall, keeping all files. It can — it's a config switch that
reuses the existing hardware-configuration.nix, not a reformat. Adds
docs/MIGRATION.md: a generic "existing NixOS → Nomarchy" walkthrough with
TuringMachine as the worked example — candidacy checklist, the two
data-safety rules (never bump system.stateVersion; /home untouched), a
reversible Phase 0→4 (btrfs snapshot → build-only gate → nixos-rebuild
test → reconcile → cutover) and a triple rollback net. Bakes his decisions:
Nomarchy PPD (drop all ryzenadj), no Secure Boot (drop lanzaboote), full
cutover. Flake/system/home examples verified against lib.nix mkFlake +
templates/downstream, not guessed.
Also files a PROPOSED note: home.stateVersion should be mkDefault so
migrating users don't need mkForce.
