If a client socket is remotely lost but the client is not sent an RST in
response to the next request, the socket might sit in RTO for extended
lengths of time, resulting in "no internet" for users. Instead, timeout
after 10s, which will close the underlying socket, recovering from the
situation more promptly.

Update vite to 5.1.4, and vitest to 1.3.1 (their latest versions). Also
remove vite-plugin-rewrite-all as this is no longer necessary with vite

An increasing number of users have very large subnet route
configurations, which can produce very large amounts of log data when
WireGuard is reconfigured. The logs don't contain the actual routes, so
they're largely useless for diagnostics, so we'll just suppress them.

The derper sends an in-protocol keepalive every 60-65s, so frequent TCP
keepalives are unnecessary. In this tuning TCP keepalives should never
occur for a DERP client connection, as they will send an L7 keepalive
often enough to always reset the TCP keepalive timer. If however a
connection does not receive an ACK promptly it will now be shutdown,
which happens sooner than it would with a normal TCP keepalive tuning.
This re-tuning reduces the frequency of network traffic from derp to
client, reducing battery cost.

This package uses a count-min sketch and a heap to track the top K items
in a stream of data. Tracking a new item and adding a count to an
existing item both require no memory allocations and is at worst
O(log(k)) complexity.

Looking at profiles, we spend a lot of time in winipcfg.LUID.DeleteRoute
looking up the routing table entry for the provided RouteData.
But we already have the row! We previously obtained that data via the full
table dump we did in getInterfaceRoutes. We can make this a lot faster by
hanging onto a reference to the wipipcfg.MibIPforwardRow2 and executing
the delete operation directly on that.

* tsweb: update ServeMux matching to 1.22.0 syntax
Updates #cleanup
Go 1.22.0 introduced the ability to use more expressive routing patterns
that include HTTP method when constructing ServeMux entries.
Applications that attempted to use these patterns in combination with
the old `tsweb.Debugger` would experience a panic as Go would not permit
the use of matching rules with mixed level of specificity. We now
specify the method for each `/debug` handler to prevent
incompatibilities.

* cmd/k8s-operator,k8s-operator: introduce proxy configuration mechanism via ProxyClass custom resource.
ProxyClass custom resource can be used to specify customizations
for the proxy resources created by the operator.
Add a reconciler that validates ProxyClass resources
and sets a Ready condition to True or False with a corresponding reason and message.
This is required because some fields (labels and annotations)
require complex validations that cannot be performed at custom resource apply time.
Reconcilers that use the ProxyClass to configure proxy resources are expected to
verify that the ProxyClass is Ready and not proceed with resource creation
if configuration from a ProxyClass that is not yet Ready is required.
If a tailscale ingress/egress Service is annotated with a tailscale.com/proxy-class annotation, look up the corresponding ProxyClass and, if it is Ready, apply the configuration from the ProxyClass to the proxy's StatefulSet.
If a tailscale Ingress has a tailscale.com/proxy-class annotation
and the referenced ProxyClass custom resource is available and Ready,
apply configuration from the ProxyClass to the proxy resources
that will be created for the Ingress.
Add a new .proxyClass field to the Connector spec.
If connector.spec.proxyClass is set to a ProxyClass that is available and Ready,
apply configuration from the ProxyClass to the proxy resources created for the Connector.
Ensure that when Helm chart is packaged, the ProxyClass yaml is added to chart templates. Ensure that static manifest generator adds ProxyClass yaml to operator.yaml. Regenerate operator.yaml
