Adds a CLI subcommand that downloads a signed Tailscale appliance
image (Gokrazy archive format, GAF) from pkgs.tailscale.com,
constructs a fresh GPT-partitioned disk from it (mbr.img + a
synthesized partition table + boot.img + root.img), formats /perm
as ext4 in pure Go via go-diskfs, and ejects the disk so a user
running on a regular workstation can flash an SD card or homelab
VM disk in one command without installing e2fsprogs.
On macOS the target disk is auto-discovered via diskutil, skipping
the boot disk and anything bigger than 256 GB out of paranoia. On
Linux the user passes --disk=/dev/sdX explicitly. Windows is not
supported yet and the command returns an error.
The GPT layout matches monogok's full-disk layout via the new
public github.com/bradfitz/monogok/disklayout package; a drift-
guard test inside monogok asserts the two implementations stay
byte-identical so OTA updates against monogok-built images keep
working.
Behind a ts_omit_flashappliance build tag (on by default).

Builds on top of the unsigned URL-based GAF update flow added previously
(see referenced issue for context). The pkgs.tailscale.com server now
publishes signed GAFs for the unstable track, with detached ed25519
signatures produced by pkgsign's signdist path (the same distsign scheme
used for every other release artifact). This change consumes them.
The URL-based path (tailscale update --gokrazy-update-from-url=URL) now
verifies the signature by default using clientupdate/distsign.Client,
which fetches distsign.pub from the root of the host serving the GAF and
checks the .sig against the root keys embedded in this binary. The
--unsigned flag stays for TestGokrazyUpdatesItselfToSameImage, whose
in-test fileserver does not publish distsign.pub.
The bare tailscale update path is now wired up for the Tailscale
appliance image. It fetches <pkgs>/<track>/?mode=json, picks the GAF
whose key matches the local device (vm-amd64, vm-arm64, or pi-arm64,
where arm64 is split via /sys/firmware/devicetree/base/model), confirms
the version with the user, and reuses the verified download path above.
To avoid wiping a user's custom Gokrazy build that happens to include
tailscaled, the bare update path is gated on hostinfo.Package == "tsapp",
which is only set when the new ts_appliance build tag is present
(mirroring the existing ts_package_container tag). The
gokrazy/tsapp*/config.json files now pass GoBuildTags ["ts_appliance"]
for the tailscale and tailscaled packages so monogok bakes the tag into
the official appliance builds. The TS_FORCE_ALLOW_TSAPP_UPDATE env var
is an escape hatch for callers who want to force the appliance update
path on a non-appliance build. The URL-based path stays ungated since it
requires explicit user intent (and is exercised by the natlab vmtest).

This adds support for Gokrazy GAF (Gokrazy Archive Format) zip
auto-updates, starting to wire up Tailscale's clientupdate mechanism
to Gokrazy's update mechanism.
Currently there's just a CLI command to update from a GAF URL,
with an --unsigned flag for use in a new natlab vmtest.
Next step would be publishing unstable track GAF files on
pkgs.tailscale.com, with detached signatures, and then making the
clientupdate mechanism also download those and check signatures.

This file was never truly necessary and has never actually been used in
the history of Tailscale's open source releases.
A Brief History of AUTHORS files
---
The AUTHORS file was a pattern developed at Google, originally for
Chromium, then adopted by Go and a bunch of other projects. The problem
was that Chromium originally had a copyright line only recognizing
Google as the copyright holder. Because Google (and most open source
projects) do not require copyright assignemnt for contributions, each
contributor maintains their copyright. Some large corporate contributors
then tried to add their own name to the copyright line in the LICENSE
file or in file headers. This quickly becomes unwieldy, and puts a
tremendous burden on anyone building on top of Chromium, since the
license requires that they keep all copyright lines intact.
The compromise was to create an AUTHORS file that would list all of the
copyright holders. The LICENSE file and source file headers would then
include that list by reference, listing the copyright holder as "The
Chromium Authors".
This also become cumbersome to simply keep the file up to date with a
high rate of new contributors. Plus it's not always obvious who the
copyright holder is. Sometimes it is the individual making the
contribution, but many times it may be their employer. There is no way
for the proejct maintainer to know.
Eventually, Google changed their policy to no longer recommend trying to
keep the AUTHORS file up to date proactively, and instead to only add to
it when requested: https://opensource.google/docs/releasing/authors.
They are also clear that:
> Adding contributors to the AUTHORS file is entirely within the
> project's discretion and has no implications for copyright ownership.
It was primarily added to appease a small number of large contributors
that insisted that they be recognized as copyright holders (which was
entirely their right to do). But it's not truly necessary, and not even
the most accurate way of identifying contributors and/or copyright
holders.
In practice, we've never added anyone to our AUTHORS file. It only lists
Tailscale, so it's not really serving any purpose. It also causes
confusion because Tailscalars put the "Tailscale Inc & AUTHORS" header
in other open source repos which don't actually have an AUTHORS file, so
it's ambiguous what that means.
Instead, we just acknowledge that the contributors to Tailscale (whoever
they are) are copyright holders for their individual contributions. We
also have the benefit of using the DCO (developercertificate.org) which
provides some additional certification of their right to make the
contribution.
The source file changes were purely mechanical with:
git ls-files | xargs sed -i -e 's/\(Tailscale Inc &\) AUTHORS/\1 contributors/g'

While `clientupdate.Updater` won't be able to apply updates on macsys,
we use `clientupdate.CanAutoUpdate` to gate the EditPrefs endpoint in
localAPI. We should allow the GUI client to set AutoUpdate.Apply on
macsys for it to properly get reported to the control plane. This also
allows the tailnet-wide default for auto-updates to propagate to macsys
clients.

Previously, we would only compare the current version to resolved latest

According to
https://learn.microsoft.com/en-us/windows/win32/msi/standard-installer-command-line-options#promptrestart,
`/promptrestart` is ignored with `/quiet` is set, so msiexec.exe can
sometimes silently trigger a reboot. The best we can do to reduce
unexpected disruption is to just prevent restarts, until the user
chooses to do it. Restarts aren't normally needed for Tailscale updates,
but there seem to be some situations where it's triggered.

When we run tailscled under systemd, restarting the unit kills all child
processes, including "tailscale update". And during update, the package
manager will restart the tailscaled unit. Specifically on Debian-based
distros, interrupting `apt-get install` can get the system into a wedged
state which requires the user to manually run `dpkg --configure` to
recover.
To avoid all this, use `systemd-run` where available to run the
`tailscale update` process. This launches it in a separate temporary
unit and doesn't kill it when parent unit is restarted.
Also, detect when `apt-get install` complains about aborted update and
try to restore the system by running `dpkg --configure tailscale`. This
could help if the system unexpectedly shuts down during our auto-update.

When updating via c2n, `tailscale.exe update` runs from `tailscaled.exe`
which runs as SYSTEM. The MSI installer does not start the GUI when

Instead, always ask the MSI installer to not launch the GUI (via
`TS_NOLAUNCH` argument) and launch it manually with a token from the
current logged in user. The token code was borrowed from
