https://github.com/tailscale/tailscale/pull/17346 moved the kube and aws
arn store initializations to feature/condregister, under the assumption
that anything using it would use kubestore.New. Unfortunately,
cmd/k8s-proxy makes use of store.New, which compares the `<prefix>:`
supplied in the provided `path string` argument against known stores. If
it doesn't find it, it fallsback to using a FileStore.
Since cmd/k8s-proxy uses store.New to try and initialize a kube store in
some cases (without importing feature/condregister), it silently creates
a FileStore and that leads to misleading errors further along in
execution.
This fixes this issue by importing condregister, and successfully
initializes a kube store.

The Tailscale CLI is the primary configuration interface and as such it
is used in scripts, container setups, and many other places that do not
have a terminal available and should not be made to respond to prompts.
The default is set to false where the "risky" API is being used by the
CLI and true otherwise, this means that the `--yes` flags are only
required under interactive runs and scripts do not need to be concerned
with prompts or extra flags.

In Dec 2021 in d3d503d997 I had grand plans to make exit node DNS
cheaper by using HTTP/2 over PeerAPI, at least on some platforms. I
only did server-side support though and never made it to the client.
In the ~4 years since, some things have happened:
* Go 1.24 got support for http.Protocols (https://pkg.go.dev/net/http#Protocols)
and doing UnencryptedHTTP2 ("HTTP2 with prior knowledge")
* The old h2c upgrade mechanism was deprecated; see https://github.com/golang/go/issues/63565
and https://github.com/golang/go/issues/67816
* Go plans to deprecate x/net/http2 and move everything to the standard library.
So this drops our use of the x/net/http2/h2c package and instead
enables h2c (on all platforms now) using the standard library.
This does mean we lose the deprecated h2c Upgrade support, but that's
fine.
If/when we do the h2c client support for ExitDNS, we'll have to probe
the peer to see whether it supports it. Or have it reply with a header
saying that future requests can us h2c. (It's tempting to use capver,
but maybe people will disable that support anyway, so we should
discover it at runtime instead.)
Also do the same in the sessionrecording package.

When I added dependency support to featuretag, I broke the handling of
the non-omit build tags (as used by the "box" support for bundling the
CLI into tailscaled). That then affected depaware. The
depaware-minbox.txt this whole time recently has not included the CLI.
So fix that, and also add a new depaware variant that's only the
daemon, without the CLI.

Otherwise they're uselessly imported by tsnet applications, even

already had to explicitly import them and use kubestore.New or

This commit fixes a race condition where `tailscale up --force-reauth` would
exit prematurely on an already-logged in device.
Previously, the CLI would wait for IPN to report the "Running" state and then
exit. However, this could happen before the new auth URL was printed, leading
to two distinct issues:
* **Without seamless key renewal:** The CLI could exit immediately after
the `StartLoginInteractive` call, before IPN has time to switch into
the "Starting" state or send a new auth URL back to the CLI.
* **With seamless key renewal:** IPN stays in the "Running" state
throughout the process, so the CLI exits immediately without performing
any reauthentication.
The fix is to change the CLI's exit condition.
Instead of waiting for the "Running" state, if we're doing a `--force-reauth`
we now wait to see the node key change, which is a more reliable indicator
that a successful authentication has occurred.

This partially reverts f3d2fd2.
When that patch was written, the goroutine that responds to IPN notifications
could call `StartLoginInteractive`, creating a race condition that led to
flaky integration tests. We no longer call `StartLoginInteractive` in that
goroutine, so the race is now impossible.
Moving the `WatchIPNBus` call earlier ensures the CLI gets all necessary
IPN notifications, preventing a reauth from hanging.

A customer wants to allow their employees to restart tailscaled at will, when access rights and MDM policy allow it,
as a way to fully reset client state and re-create the tunnel in case of connectivity issues.
On Windows, the main tailscaled process runs as a child of a service process. The service restarts the child
when it exits (or crashes) until the service itself is stopped. Regular (non-admin) users can't stop the service,
and allowing them to do so isn't ideal, especially in managed or multi-user environments.
In this PR, we add a LocalAPI endpoint that instructs ipnserver.Server, and by extension the tailscaled process,
to shut down. The service then restarts the child tailscaled. Shutting down tailscaled requires LocalAPI write access
and an enabled policy setting.

Ideally we would remove this warning entirely, as it is now possible to
reauthenticate without losing connectivty. However, it is still possible to
lose SSH connectivity if the user changes the ownership of the machine when
they do a force-reauth, and we have no way of knowing if they are going to
do that before they do it.
For now, let's just reduce the strength of the warning to warn them that
they "may" lose their connection, rather than they "will".

In MacOS GUI apps, users have to select folders to share via the GUI. This is both because
the GUI app keeps its own record of shares, and because the sandboxed version of the GUI
app needs to gain access to the shared folders by having the user pick them in a file
selector.
The new build tag `ts_mac_gui` allows the MacOS GUI app build to signal that this
is a MacOS GUI app, which causes the `drive` subcommand to be omitted so that people
do not mistakenly attempt to use it.
