global impl
This is step 4 of making syspolicy a build-time feature.
This adds a policyclient.Get() accessor to return the correct
implementation to use: either the real one, or the no-op one. (A third
type, a static one for testing, also exists, so in general a
policyclient.Client should be plumbed around and not always fetched
via policyclient.Get whenever possible, especially if tests need to use
alternate syspolicy)

leaf package
Step 3 in the series. See earlier cc532efc2000 and d05e6dc09e.
This step moves some types into a new leaf "ptype" package out of the
big "settings" package. The policyclient.Client will later get new
methods to return those things (as well as Duration and Uint64, which
weren't done at the time of the earlier prototype).

Previously, when attempting a risky action, the CLI printed a 5 second countdown saying
"Continuing in 5 seconds...". When the countdown finished, the CLI aborted rather than
continuing.
To avoid confusion, but also avoid accidentally continuing if someone (or an automated
process) fails to manually abort within the countdown, we now explicitly prompt for a
y/n response on whether or not to continue.

This is step 2 of ~4, breaking up #14720 into reviewable chunks, with
the aim to make syspolicy be a build-time configurable feature.
Step 1 was #16984.
In this second step, the util/syspolicy/policyclient package is added
with the policyclient.Client interface. This is the interface that's
always present (regardless of build tags), and is what code around the
tree uses to ask syspolicy/MDM questions.
There are two implementations of policyclient.Client for now:
1) NoPolicyClient, which only returns default values.
2) the unexported, temporary 'globalSyspolicy', which is implemented
in terms of the global functions we wish to later eliminate.
This then starts to plumb around the policyclient.Client to most callers.
Future changes will plumb it more. When the last of the global func
callers are gone, then we can unexport the global functions and make a
proper policyclient.Client type and constructor in the syspolicy
package, removing the globalSyspolicy impl out of tsd.
The final change will sprinkle build tags in a few more places and
lock it in with dependency tests to make sure the dependencies don't
later creep back in.

This is step 1 of ~3, breaking up #14720 into reviewable chunks, with
the aim to make syspolicy be a build-time configurable feature.
In this first (very noisy) step, all the syspolicy string key
constants move to a new constant-only (code-free) package. This will
make future steps more reviewable, without this movement noise.
There are no code or behavior changes here.
The future steps of this series can be seen in #14720: removing global
funcs from syspolicy resolution and using an interface that's plumbed
around instead. Then adding build tags.

(#16881)
Add a ternary flag that unless set explicitly to false keeps the
insecure behavior of TSIDP.
If the flag is false, add functionality on startup to migrate
oidc-funnel-clients.json to oauth-clients.json if it doesn’t exist.
If the flag is false, modify endpoints to behave similarly regardless
of funnel, tailnet, or localhost. They will all verify client ID & secret
when appropriate per RFC 6749. The authorize endpoint will no longer change
based on funnel status or nodeID.
Add extra tests verifying TSIDP endpoints behave as expected
with the new flag.
Safely create the redirect URL from what's passed into the
authorize endpoint.

DERP writes go via TCP and the host OS will have plenty of buffer space.
We've observed in the wild with a backed up TCP socket kernel side
buffers of >2.4MB. The DERP internal queue being larger causes an
increase in the probability that the contents of the backbuffer are
"dead letters" - packets that were assumed to be lost.
A first step to improvement is to size this queue only large enough to
avoid some of the initial connect stall problem, but not large enough
that it is contributing in a substantial way to buffer bloat /
dead-letter retention.

The serve code leaves it up to the system's DNS resolver and netstack to
figure out how to reach the proxy destination. Combined with k8s-proxy
running in userspace mode, this means we can't rely on MagicDNS being
available or tailnet IPs being routable. I'd like to implement that as a
feature for serve in userspace mode, but for now the safer fix to get
kube-apiserver ProxyGroups consistently working in all environments is to
switch to using localhost as the proxy target instead.
This has a small knock-on in the code that does WhoIs lookups, which now
needs to check the X-Forwarded-For header that serve populates to get
the correct tailnet IP to look up, because the request's remote address
will be loopback.

Add the ability for operators of natc in consensus mode to remove
servers from the raft cluster config, without losing other state.
Updates #14667
Signed-off-by: Fran Bull <fran@tailscale.com>

Currently consensus has a bootstrap routine where a tsnet node tries to
join each other node with the cluster tag, and if it is not able to join
any other node it starts its own cluster.
That algorithm is racy, and can result in split brain (more than one
leader/cluster) if all the nodes for a cluster are started at the same
time.
Add a FollowOnly argument to the bootstrap function. If provided this
tsnet node will never lead, it will try (and retry with exponential back
off) to follow any node it can contact.
Add a --follow-only flag to cmd/natc that uses this new tsconsensus
functionality.
Also slightly reorganize some arguments into opts structs.

This adds support for having every viewer type implement
jsonv2.MarshalerTo and jsonv2.UnmarshalerFrom.
This provides a significant boost in performance
as the json package no longer needs to validate
the entirety of the JSON value outputted by MarshalJSON,
nor does it need to identify the boundaries of a JSON value
in order to call UnmarshalJSON.
For deeply nested and recursive MarshalJSON or UnmarshalJSON calls,
this can improve runtime from O(N²) to O(N).
This still references "github.com/go-json-experiment/json"
instead of the experimental "encoding/json/v2" package
now available in Go 1.25 under goexperiment.jsonv2
so that code still builds without the experiment tag.
Of note, the "github.com/go-json-experiment/json" package
aliases the standard library under the right build conditions.

nodes from status output
Previously, we used a non-nil Location as an indicator that a peer is a Mullvad exit node.
However, this is not, or no longer, reliable, since regular exit nodes may also have a non-nil Location,
such as when traffic steering is enabled for a tailnet.
In this PR, we update the plaintext `tailscale status` output to omit only Mullvad exit nodes, rather than all
exit nodes with a non-nil Location. The JSON output remains unchanged and continues to include all peers.
