GuofangandClaude Sonnet 5.5 48c4477ec4 Update vm-images: audit-mode base image

GuofangandClaude Sonnet 5.5 a920ba0ca5 Windows launcher only creates a differential disk; seed via Unattend.xml 
run-windows11.py no longer installs Windows or touches ISO/img files: it
creates a QCOW2 overlay on the base image (made by vm-images/build-windows-base.sh)
and, when the disk is created, mounts seed.iso. Windows reads the Unattend.xml
in its root during the specialize and OOBE passes (host name, account, auto
logon, Remote Desktop) and Configure-Windows.ps1 then installs OpenSSH with the
host's key, turns off Windows Update and copies the installer scripts.

The VM hardware uses devices with inbox Windows drivers (IDE/NVMe, e1000e,
ramfb on arm64), since the base image has no VirtIO drivers. Autounattend.xml
moves to vm-images; the vm-images pointer is updated.

GuofangandClaude Sonnet 5.5 fe7250870e Attach the cloud-init seed ISO only when the VM disk is created 
cloud-init reads the seed on the first boot only, so the Linux launchers now
mount it just for the run that creates the overlay disk. The seed drive moves
from the config files to the launcher arguments.

With `--download-only`, a launcher only downloads the media it would fetch

./run-windows11.py
```
It creates a persistent 64G disk at `vm/windows11/disk.qcow2`, automatically
partitions it, completes OOBE, creates the local administrator `guofang` with
the initial password `wang`, and enables Remote Desktop on
`0.0.0.0:3389` (all host interfaces; connect to `localhost:3389` on the host itself). During the first login it also silently installs the VirtIO
drivers (the guest tools installer on amd64, the Arm64 driver packages from the
VirtIO ISO with `pnputil` on arm64), without which the guest has no network on
arm64. The installer includes the VirtIO drivers, SPICE vdagent, and QEMU Guest
Agent. The launcher exposes the vdagent channel for host/guest clipboard
integration and the QEMU Guest Agent at `vm/windows11/qemu-guest-agent.sock`.
Change the password after first login. The OpenSSH Server is installed during
the first logon from the Win32-OpenSSH zip for the host architecture, which the
seed ISO carries (downloaded by `vm-images/download-images.sh openssh-win`), so
Windows Update is not needed. Connect with `ssh guofang@localhost -p 2222`; the
seed ISO also carries the host's SSH public key (`$SSH_PUBLIC_KEY_FILE`, else the
first of `~/.ssh/id_ed25519.pub`, `id_ecdsa.pub`, `id_rsa.pub`) for passwordless
administrator login.
It creates a persistent 64G disk at `vm/windows11/disk.qcow2` as a QCOW2
overlay on the base image and nothing else: the launcher only creates the
differential disk and starts QEMU. The base image is generic and holds nothing
but Windows (see `vm-images/README.md`): no account, no SSH, no VirtIO or other
hardware-specific drivers, no machine identity. Like a cloud image, each VM is
configured on its first boot, from the seed ISO.
Whenever the disk does not exist yet, the launcher also mounts the seed ISO
`vm/windows11/seed.iso` (beside the disk; built from `seediso/windows11/` when
missing or outdated, with the OpenSSH zip and the host's SSH public key,
`$SSH_PUBLIC_KEY_FILE` or the first of `~/.ssh/id_ed25519.pub`, `id_ecdsa.pub`,
`id_rsa.pub`). Windows reads the `Unattend.xml` in the root of that CD-ROM
during its specialize and OOBE passes: host name `WIN11`, time zone, Remote
Desktop on `0.0.0.0:3389` (all host interfaces; connect to `localhost:3389` on
the host itself), the local administrator `guofang` (initial password `wang`;
change it after first login) and automatic logon. At the first logon it runs
`Configure-Windows.ps1` from the seed ISO, which installs the OpenSSH Server
from the zip with the SSH key (connect with `ssh guofang@localhost -p 2222`),
turns off Windows Update and copies the numbered installer scripts
(`seediso/windows11/NN-*.bat` and `.ps1`) to the desktop folder `Tools`. Later
starts do not mount the seed ISO.
Because the image has no VirtIO drivers, the VM only uses devices that Windows
has inbox drivers for: an IDE disk and e1000e NIC on amd64, an NVMe disk, e1000e
NIC and ramfb display on arm64 (a fixed-size framebuffer there). The SPICE
vdagent and QEMU Guest Agent come with the VirtIO guest tools, so host/guest
clipboard integration and the guest agent are not available unless you install
those tools in the VM yourself.
The Windows VM hardware (8G memory, 8 CPUs, system disk, devices)
is defined in `qemu/windows11/config.ini`, with the accelerators and machine type in
`qemu/windows11/<os>-<arch>.ini`; the launcher renders the former to
`vm/windows11/qemu.ini` and loads both with `-readconfig`. Only the network
(see Port forwards) and the installation media are still set by the launcher. QEMU arguments after
(see Port forwards) and the seed ISO are still set by the launcher. QEMU arguments after
`--` override the config files, for example `./run-windows11.py -- -m 4G -smp 4`.
The generated answer-file ISO is stored beside the disk as
`vm/windows11/seed.iso`.
To install from the Windows ISO instead, use `./run-windows11.py
--install-from-iso`. This choice only applies while creating a missing system
disk; subsequent starts always boot the existing system disk normally. During
ISO installation, the launcher resolves its tools ISO through the shared image
helper and downloads it when missing. Override the base QCOW2, source ISO,
tools ISO, RDP port, or SSH port with the `WIN11_VM_` environment
variables shown by `./run-windows11.py --help`. For example, when the VirtIO ISO
is elsewhere:
```bash
WIN11_VM_TOOLS_ISO=/custom/path/virtio-win.iso ./run-windows11.py --install-from-iso
```
The launcher has no installation options and stops with a hint if the base image
is missing. Make the base image once with `vm-images/build-windows-base.sh`,
which is self-contained in `vm-images/` (its own answer file, QEMU config and
installation logic, written in bash): it installs Windows unattended from the
ISO into a scratch disk, runs `sysprep` as its last step and stores the disk as
the read-only base image. Override the base QCOW2, seed ISO, RDP port, or SSH
port with the `WIN11_VM_` environment variables shown by
`./run-windows11.py --help`.

The VM hardware (accelerator, memory, CPUs, drives, devices) is defined in
qemu/windows11/config.ini, which is rendered to qemu.ini in the state directory and
loaded with QEMU's -readconfig, followed by qemu/windows11/<os>-<arch>.ini (os is linux or darwin, arch is amd64 or arm64, chosen from the host system and
architecture, --arch or VM_IMAGE_ARCH). Later QEMU arguments override them, e.g. -- -m 4G -smp 4.
Use --install-from-iso to perform an automatic ISO installation instead, or
--install-from-img to install from a disk image built from the ISO.
If it exists, start Windows normally without attaching installation media.
Options:
--daemon Run QEMU in the background
--download-only Download the VirtIO tools ISO and the Windows 11 ISO
(for --arch) if they are missing, then exit; needs
Node.js and Chromium for the latter, see vm-images/README.md
(the base QCOW2 is supplied manually)
--seed-only Build the seed ISO (answer file and setup scripts) and exit,
without starting the VM or fetching the Windows and VirtIO ISOs
--install-from-iso Install from ISO when the system disk is missing
--install-from-img Like --install-from-iso, but install from the disk image
made by vm-images/build-windows-install-disk.sh, which
is the ISO path ending in .img instead of .iso.
It is attached as an NVMe disk, much faster than the

If the system disk (DIR/disk.qcow2, see --state-dir) is missing, create it as a
QCOW2 overlay on the Windows 11 base image, which starts in seconds and runs the
specialize and OOBE passes of its answer file on the first boot, and mount the
seed ISO (DIR/seed.iso, built from seediso/windows11 if missing or outdated):
Windows reads its Unattend.xml from the root of that CD-ROM during the specialize
and OOBE passes: host name, account, auto logon, Remote Desktop, then at the
first logon Configure-Windows.ps1 (OpenSSH and the SSH key, settings, installer
scripts on the desktop). If the disk exists, start Windows normally, without the
seed ISO.
Make the base image once with vm-images/build-windows-base.sh; it installs
Windows from the ISO and generalizes the result. The base image contains only
Windows (no account, no SSH, no VirtIO or other hardware-specific drivers), so
the devices in qemu/windows11 are ones Windows has inbox drivers for.
The VM hardware (accelerator, memory, CPUs, drives, devices) is defined in
qemu/windows11/config.ini, which is rendered to qemu.ini in the state directory and
loaded with QEMU's -readconfig, followed by qemu/windows11/<os>-<arch>.ini (os is linux or darwin, arch is amd64 or arm64, chosen from the host system and
architecture, --arch or VM_IMAGE_ARCH). Later QEMU arguments override them, e.g. -- -m 4G -smp 4.
Options:
--daemon Run QEMU in the background
--vnc[=ADDR:N] Serve the screen over VNC instead of opening a window, on
ADDR (default: 127.0.0.1) at TCP port 5900+N (default N: 0).
Overrides WIN11_VM_DISPLAY
--arch ARCH Guest architecture: arm64 or amd64 (default: the host's;
overrides VM_IMAGE_ARCH). A guest that differs from the
host runs under slow TCG emulation
--state-dir DIR Directory for the VM disk and runtime files
(default: vm/windows11; overrides WIN11_VM_STATE_DIR)
--rdp-port PORT Host port of the RDP rule in the port forward file
(default: 3389; overrides WIN11_VM_RDP_PORT)
--ssh-port PORT Host port of the SSH rule in the port forward file
(default: 2222; overrides WIN11_VM_SSH_PORT)
-h, --help Show this help
Environment variables:
WIN11_VM_BASE_IMAGE Windows 11 base QCOW2 image (default: beside shared images)
WIN11_VM_RDP_PORT Host RDP port (default: from the port forward file, 3389)
