Bernardo Magri 528447cc19 feat: smarter installer + Nomarchy os-release rebrand ...

Hardware:
- New installer/hardware-db.sh: flat regex table mapping sys_vendor +
  product_name to nixos-hardware modules (Framework, Dell, Lenovo, Surface,
  ASUS, Apple T2, System76).
- install.sh:select_hardware now auto-detects CPU vendor, GPU vendor, chassis
  type, and known model, then offers Accept / Add / Override. Manual menu
  retained as a fallback.
- Fixes a latent bug where HARDWARE_MODULES used literal "\n" inside a
  heredoc, producing invalid Nix.

Downstream flake:
- Capture the running Nomarchy commit and pin `nomarchy.url` to it so the
  installed system can't drift onto a newer breaking main.
- Prompt for a real hostname; nixosConfigurations.<hostname> replaces the
  generic .default. networking.hostName lands in system.nix.
- Generated flake now derives a single `pkgs` from nixpkgs + Nomarchy's
  `overlays.default` and shares it between nixosSystem and the standalone
  homeManagerConfiguration so dotfile-fast-iteration with nomarchy-env-update
  stays separate from `nixos-rebuild` while still seeing Nomarchy packages.
- `nix flake lock` runs in /mnt/etc/nixos before nixos-install so first boot
  consumes the resolved set.
- Post-install, run home-manager switch inside `nixos-enter` via runuser so
  the user's first login already has dotfiles. Failure is non-fatal.

Disk layout:
- /boot bumped to 1 GiB (was 512 MiB; tight with multi-generation kernels).
- New @snapshots subvolume at /.snapshots for snapper/btrbk/rollback.
- LUKS passphrase moved from /tmp/secret.key to /dev/shm/nomarchy-luks.key
  (tmpfs), shredded after disko, LUKS_PASSWORD unset.

Branding:
- New core/system/branding.nix sets system.nixos.distroId = "nomarchy" and
  distroName = "Nomarchy". /etc/os-release now reports Nomarchy, so fastfetch
  and other os-release readers show the right name.

Cleanup:
- flake.nix exposes `overlays.default = nomarchyOverlay` for downstream use.
- Trailing duplicated `main "$@"` + orphan `}` removed from install.sh.
