Canonical, agent-agnostic procedure for bringing a new box into the
flake, from a booted installer through to a deployable system, plus a
thin Claude Code skill pointing at it -- same split as the nixpkgs
upgrade procedure.
Records the conventions that were not written down anywhere: sgdisk
plus an LVM PV for the nix and persist volumes, adopting the
installer's SSH host keys so secrets can be encrypted before first
boot, and taking whatever show-hw-config emits that the flake's own
modules do not already set.
Also notes in AGENTS.md that a changed recipient list should be
re-encrypted per file with ragenix --rekey-one; --rekey rewrites every
secret in secrets/ and buries the actual change.

The ISO target had drifted from nixpkgs and no longer evaluated:
`iso-image.nix` now defines `image.baseName` itself, which conflicts
with ours, so force it.
Drop the `boot.initrd.systemd.enable = false` override from the
`asISO` build target. The missing `/dev/root` it worked around is no
longer an issue, and scripted initrd is deprecated for removal in
26.11.
Replace the wpa_supplicant stanza, which upstream's
`installation-device.nix` no longer carries, with NetworkManager.
Keep it out of `multi-user.target` so nothing network-related starts
until asked; NetworkManager enables wpa_supplicant as its backend,
which is D-Bus activated on demand.
Pick up three more bits from that profile: the installer
`variant_id`, the pstore drop-in that stops an install evacuating the
target's persistent entries, and the mdadm `PROGRAM` stub that
silences the unset-mail warning.
Built and booted as an ISO to confirm.
