Image builds have been dying with "Argument list too long" from sed, mktemp
and timeout alike -- commands whose argv is trivial, which is the tell that it
was the environment that had grown, not the arguments.
The X11 forwarding hint is looked up with `ls -t /tmp/.vmix-display-* | head -1`.
Under nullglob a non-matching pattern is removed from the command line rather
than passed through literally, so `ls -t` runs with no arguments at all and
lists the working directory instead. In a nix build that directory is the
build tree, whose newest file is nix's own env-vars dump. The result is that
VMIX_DF becomes "env-vars", the SDL branch is taken on a machine with no X at
all, and DISPLAY is exported with a slice of the env dump inside it. From that
line onward every exec in the build fails with E2BIG.
find does the same lookup without depending on how the shell treats an
unmatched pattern, and -type f keeps a stray directory out of it.

Three things, all in service of putting Proxmox in a VM that can still hand a
GPU to its own guests, and of a Windows VM whose profile survives its OS disk.
pci.viommu.enable emits `-device intel-iommu,intremap=on,caching-mode=on` and
forces kernel-irqchip=split, which interrupt remapping requires. Without an
IOMMU of its own a guest cannot bind a passed-through device to vfio-pci, so
it can never forward one on. The device leads the command line because QEMU
realizes devices in order and intel-iommu must precede what it translates.
pci.vgaPassthrough (default true, so nothing changes for existing VMs) makes
x-vga=on optional. It was forced on the first passthrough device, which is
wrong for a card the guest only forwards onward: it claims the VGA path the
emulated console adapter needs.
customizeImage gains extraDisk, a blank disk attached for the Audit Mode boot
and emitted as the derivation's `data` output. generalize uses it for dataDisk
and profilesDirectory, so the disk is partitioned and the profile relocated
under OOBE in the build VM. That is what removes the need for delayOobeRun --
previously the volume ProfilesDirectory names could not exist until the image
reached real hardware. A second output rather than a directory keeps ${image}
meaning the OS qcow2 for every existing consumer.
generalize also picks up staticIP and profilesDirectory.

- Switch MAS from /HWID to /Z-Windows (TSforge ZeroCID) which is
hardware-independent and survives VM migration
- Re-install product key and restart SPP service before TSforge
to restore licensing state after sysprep
- Add nicModel option to customizeImage and generalize for images
without VirtIO drivers
- Update MAS activation script to latest version

Allows overriding the QEMU NIC model during builds (e.g. e1000 for
images without VirtIO drivers). Enables MAS activation on upstream
images that lack VirtIO network drivers.

Copy Xauthority to a world-readable temp file so nix build users
(nixbld*) can authenticate to X11. Add --option sandbox relaxed so
__noChroot derivations can access the X11 socket and xauth file.

Laptop images now use AHCI storage + e1000 network instead of VirtIO.
This fixes "inaccessible boot device" on real hardware — the AHCI→NVMe
driver transition is handled by Windows, unlike VirtIO→NVMe which isn't.
- makeImage: useAHCI flag switches disk to ide-hd and network to e1000
- customizeImage: auto-detects useAHCI from original image, propagates it
- win10/win11 laptop images: useAHCI = true
- vmix run: --ahci flag for running laptop images in QEMU
- generalize: PlainText password tags in OOBE unattend XML

SDL display:
- try SDL, auto-fallback to headless if it fails (no crash)
- SDL_VIDEODRIVER=x11 to avoid wayland socket path issues
- suppress XDG_RUNTIME_DIR warnings
Disk copy:
- zap-all before writing to clear old partition tables
- delete recovery partition (4) before resizing partition 3
- use parted resizepart (preserves partition GUID for BCD)
- remote: nix-shell for sgdisk/parted/ntfsresize on target
- remote: lz4 compression for faster streaming
- remote: pv progress bar with disk size
- -y/--yes flag to skip confirmation prompt
Generalize:
- delay-oobe-run=true defers OOBE + activation to real hardware
- clean cached Autounattend from Windows\Panther before sysprep
- taskkill sysprep.exe on first login (CopyProfile artifact)

CLI:
- `vmix run <qcow2>` boots image with QEMU (SDL if DISPLAY, snapshot mode)
- --generalize supports delay-oobe-run=true to defer OOBE + activation
to first boot on real hardware (for physical disk deployments)
Templates:
- essentials.virtioDrivers: installs VirtIO drivers only (no guest agent)
used in laptop bundle for network access during Office download
- generalize: delayOobeRun flag controls sysprep /shutdown vs /reboot
delays OOBE, user creation and HWID activation to target device
Build:
- suppress XDG_RUNTIME_DIR and homeless-shelter warnings in SDL mode
- remove invalid ICH9-LMB global properties
