Owner

Rebased onto current dev (was branched at 59e8a9d, 2026-09-06). Single commit, unchanged in content — it's been sitting unmerged while the douro ran from it.

Gives the douro the same run-from-USB shape batm3 already has: lifts the batm3-usb module and image post-processing into shared usbBootModule / mkUsbDiskImage helpers, then adds nixosConfigurations.douro-usb and packages.disk-image-douro-usb on top of douro-installed. batm3-usb evaluates to the same fileSystems/upgrade config as before.

Needed in dev before the douro can be rebuilt from dev at all — #douro-usb doesn't exist there today. nix eval .#nixosConfigurations.douro-usb.config.system.build.toplevel.drvPath succeeds after the rebase.

feat(deploy): USB-bootable douro image (disk-image-douro-usb) 23fe4a59f1

The douro cutover to bitspire is being done remotely with a USB stick
and the machine's internal drive is not NixOS, so the stick has to be
the system rather than an installer medium. Give douro the same
run-from-USB shape batm3 already has.

flake.nix
- Lift the batm3-usb module and image post-processing into shared
  `usbBootModule` / `mkUsbDiskImage` helpers (distinct nixos-usb/ESP-USB
  labels, nofail /boot, no growPartition, autoUpgrade off, ESP relabel).
  batm3-usb evaluates to the same fileSystems/upgrade config as before.
- Add `nixosConfigurations.douro-usb` and
  `packages.disk-image-douro-usb` on top of douro-installed.

douro.nix
- Blacklist uas and set usbcore.autosuspend=-1, the same bus-drop
  hardening batm3.nix carries, so a stick is a reliable boot medium on
  the Bay Trail box.

README
- Document the -usb outputs and the flash-with-Etcher, no-installer flow.
