This commit modifies the kubernetes operator to use the `tailscale-client-go-v2`
package instead of the internal tailscale client it was previously using. This
now gives us the ability to expand out custom resources and features as they
become available via the API module.
The tailnet reconciler has also been modified to manage clients as tailnets
are created and removed, providing each subsequent reconciler with a single
`ClientProvider` that obtains a tailscale client for the respective tailnet
by name, or the operator's default when presented with a blank string.

Add tstest/natlab/vmtest, a high-level framework for running multi-VM
integration tests with mixed OS types (gokrazy + Ubuntu/Debian cloud
images) connected via natlab's vnet virtual network.
The vmtest package provides:
- Env type that orchestrates vnet, QEMU processes, and agent connections
- OS image support (Gokrazy, Ubuntu2404, Debian12) with download/cache
- QEMU launch per OS type (microvm for gokrazy, q35+KVM for cloud)
- Cloud-init seed ISO generation with network-config for multi-NIC
- Cross-compilation of test binaries for cloud VMs
- Debug SSH NIC on cloud VMs for interactive debugging
- Test helpers: ApproveRoutes, HTTPGet, TailscalePing, DumpStatus,
WaitForPeerRoute, SSHExec
TTA enhancements (cmd/tta):
- Parameterize /up (accept-routes, advertise-routes, snat-subnet-routes)
- Add /set, /start-webserver, /http-get endpoints
- /http-get uses local.Client.UserDial for Tailscale-routed requests
- Fix /ping for non-gokrazy systems
TestSubnetRouter exercises a 3-VM subnet router scenario:
client (gokrazy) → subnet-router (Ubuntu, dual-NIC) → backend (gokrazy)
Verifies HTTP access to the backend webserver through the Tailscale
subnet route. Passes in ~30 seconds.

It's not worth adding the v2 client just for these e2e tests. Remove
that dependency for now to keep a clear separation, but we should revive
the v2 client version if we ever decide to take that dependency for the
tailscale/tailscale repo as a whole.

Adds orchestration for more of the e2e testing setup requirements to
make it easier to run them in CI, but also run them locally in a way
that's consistent with CI. Requires running devcontrol, but otherwise
supports creating all the scaffolding required to exercise the operator

Adds cmd/cigocacher as the client to cigocached for Go caching over
HTTP. The HTTP cache is best-effort only, and builds will fall back to
disk-only cache if it's not available, much like regular builds.
Not yet used in CI; that will follow in another PR once we have runners
available in this repo with the right network setup for reaching
cigocached.

This adds the --proxy-protocol flag to 'tailscale serve' and
'tailscale funnel', which tells the Tailscale client to prepend a PROXY
protocol[1] header when making connections to the proxied-to backend.
I've verified that this works with our existing funnel servers without
additional work, since they pass along source address information via
PeerAPI already.

Add options to the eventbus.Bus to plumb in a logger.
Route that logger in to the subscriber machinery, and trigger a log message to
it when a subscriber fails to respond to its delivered events for 5s or more.
The log message includes the package, filename, and line number of the call
site that created the subscription.
Add tests that verify this works.

In #17639 we moved the subscription into NewLogger to ensure we would not race
subscribing with shutdown of the eventbus client. Doing so fixed that problem,
but exposed another: As we were only servicing events occasionally when waiting
for the network to come up, we could leave the eventbus to stall in cases where
a number of network deltas arrived later and weren't processed.
To address that, let's separate the concerns: As before, we'll Subscribe early
to avoid conflicts with shutdown; but instead of using the subscriber directly
to determine readiness, we'll keep track of the last-known network state in a
selectable condition that the subscriber updates for us. When we want to wait,
we'll wait on that condition (or until our context ends), ensuring all the
events get processed in a timely manner.

depaware was merging golang.org/x/foo and std's
vendor/golang.org/x/foo packages (which could both be in the binary!),
leading to confusing output, especially when I was working on
eliminating duplicate packages imported under different names.
This makes the depaware output longer and grosser, but doesn't hide
reality from us.

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.
