The control plane will sometimes determine that a node is not online,
while the node is still able to connect to its peers. This patch
doesn’t solve this problem, but it does mitigate it.
This PR introduces the `client-side-reachability` node attribute that
switches the node to completely ignore the online signal from control.
In the future, the client itself should collect reachability data from
active Wireguard flows and Tailscale pings.

A recent change (009d702adf) introduced a deadlock where the
/machine/update-health network request to report the client's health
status update to the control plane was moved to being synchronous
within the eventbus's pump machinery.
I started to instead make the health reporting be async, but then we
realized in the three years since we added that, it's barely been used
and doesn't pay for itself, for how many HTTP requests it makes.
Instead, delete it all and replace it with a c2n handler, which
provides much more helpful information.

For debugging purposes, add a new C2N endpoint returning the current
netmap. Optionally, coordination server can send a new "candidate" map
response, which the client will generate a separate netmap for.
Coordination server can later compare two netmaps, detecting unexpected
changes to the client state.

Previously, seamless key renewal was an opt-in feature. Customers had
to set a `seamless-key-renewal` node attribute in their policy file.
This patch enables seamless key renewal by default for all clients.
It includes a `disable-seamless-key-renewal` node attribute we can set
in Control, so we can manage the rollout and disable the feature for
clients with known bugs. This new attribute makes the feature opt-out.

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.

When a client selects a particular exit node, Control may use that as
a signal for deciding other routes.
This patch causes the client to report whenever the current exit node
changes, through tailcfg.Hostinfo.ExitNodeID. It relies on a properly
set ipn.Prefs.ExitNodeID, which should already be resolved by
`tailscale set`.

* cmd/tailscale/cli: Add service flag to serve command
This commit adds the service flag to serve command which allows serving a service and add the service
to the advertisedServices field in prefs (What advertise command does that will be removed later).
When adding proxies, TCP proxies and WEB proxies work the same way as normal serve, just under a
different DNSname. There is a services specific L3 serving mode called Tun, can be set via --tun flag.
Serving a service is always in --bg mode. If --bg is explicitly set t o false, an error message will
be sent out. The restriction on proxy target being localhost or 127.0.0.1 also applies to services.
When removing proxies, TCP proxies can be removed with type and port flag and off argument. Web proxies
can be removed with type, port, setPath flag and off argument. To align with normal serve, when setPath
is not set, all handler under the hostport will be removed. When flags are not set but off argument was
passed by user, it will be a noop. Removing all config for a service will be available later with a new
subcommand clear.

When `tailscale exit-node suggest` contacts the LocalAPI for a
suggested exit node, the client consults its netmap for peers that
contain the `suggest-exit-node` peercap. It currently uses a series of
heuristics to determine the exit node to suggest.
When the `traffic-steering` feature flag is enabled on its tailnet,
the client will defer to Control’s priority scores for a particular
peer. These scores, in `tailcfg.Hostinfo.Location.Priority`, were
historically only used for Mullvad exit nodes, but they have now been
extended to score any peer that could host a redundant resource.
Client capability version 119 is the earliest client that understands
these traffic steering scores. Control tells the client to switch to
rely on these scores by adding `tailcfg.NodeAttrTrafficSteering` to
its `AllCaps`.

For people who can't use LetsEncrypt because it's banned.
Per https://github.com/tailscale/tailscale/issues/11776#issuecomment-2520955317
This does two things:
1) if you run derper with --certmode=manual and --hostname=$IP_ADDRESS
we previously permitted, but now we also:
* auto-generate the self-signed cert for you if it doesn't yet exist on disk
* print out the derpmap configuration you need to use that
self-signed cert
2) teaches derp/derphttp's derp dialer to verify the signature of
self-signed TLS certs, if so declared in the existing
DERPNode.CertName field, which previously existed for domain fronting,
separating out the dial hostname from how certs are validates,
so it's not overloaded much; that's what it was meant for.

We are soon going to start assigning shared-in nodes a CGNAT IPv4 in the Hello tailnet when necessary, the same way that normal node shares assign a new IPv4 on conflict.
But Hello wants to display the node's native IPv4, the one it uses in its own tailnet. That IPv4 isn't available anywhere in the netmap today, because it's not normally needed for anything.
We are going to start sending that native IPv4 in the peer node CapMap, only for Hello's netmap responses. This change enables Hello to display that native IPv4 instead, when available.
