ipn/ipnlocal: don't program system DNS when node key is expired (#13370)
This mimics having Tailscale in the 'Stopped' state by programming an
empty DNS configuration when the current node key is expired.

0a2e5afb26 tsnet: remove old package doc experimental warning
It was scaring people. It's been pretty stable for quite some time now
and we're unlikely to change the API and break people at this point.
We might, but have been trying not to.

4dfde7bffc net/dns: disable DNS registration for Tailscale interface on Windows
We already disable dynamic updates by setting DisableDynamicUpdate to 1 for the Tailscale interface.
However, this does not prevent non-dynamic DNS registration from happening when `ipconfig /registerdns`
runs and in similar scenarios. Notably, dns/windowsManager.SetDNS runs `ipconfig /registerdns`,
triggering DNS registration for all interfaces that do not explicitly disable it.

In this PR, we update dns/windowsManager.disableDynamicUpdates to also set RegistrationEnabled to 0.

fd6686d81a tka: truncate long rotation signature chains
When a rotation signature chain reaches a certain size, remove the
oldest rotation signature from the chain before wrapping it in a new
rotation signature.

Since all previous rotation signatures are signed by the same wrapping
pubkey (node's own tailnet lock key), the node can re-construct the
chain, re-signing previous rotation signatures. This will satisfy the
existing certificate validation logic.

cli: implement tailscale dns status (#13353)
Updates tailscale/tailscale#13326

This PR begins implementing a `tailscale dns` command group in the Tailscale CLI. It provides an initial implementation of `tailscale dns status` which dumps the state of the internal DNS forwarder.

Two new endpoints were added in LocalAPI to support the CLI functionality:

- `/netmap`: dumps a copy of the last received network map (because the CLI shouldn't have to listen to the ipn bus for a copy)
- `/dns-osconfig`: dumps the OS DNS configuration (this will be very handy for the UI clients as well, as they currently do not display this information)

My plan is to implement other subcommands mentioned in tailscale/tailscale#13326, such as `query`, in later PRs.

5bc9fafab8 ipn/ipnlocal: always send auth URL notifications when a user requests interactive login
This PR changes how LocalBackend handles interactive (initiated via StartLoginInteractive) and non-interactive (e.g., due to key expiration) logins,
and when it sends the authURL to the connected clients.

Specifically,
 - When a user initiates an interactive login by clicking Log In in the GUI, the LocalAPI calls StartLoginInteractive.
   If an authURL is available and hasn't expired, we immediately send it to all connected clients, suggesting them to open that URL in a browser.
   Otherwise, we send a login request to the control plane and set a flag indicating that an interactive login is in progress.
 - When LocalBackend receives an authURL from the control plane, we check if it differs from the previous one and whether an interactive login
   is in progress. If either condition is true, we notify all connected clients with the new authURL and reset the interactive login flag.

We reset the auth URL and flags upon a successful authentication, when a different user logs in and when switching Tailscale login profiles.

Finally, we remove the redundant dedup logic added to WatchNotifications in #12096 and revert the tests to their original state to ensure that
calling StartLoginInteractive always produces BrowseToURL notifications, either immediately or when the authURL is received from the control plane.

We also include an internal package that tracks and reports policy usage metrics when a policy setting
is read from a store. Initially, it will be used only on Windows and Android, as macOS, iOS, and tvOS
report their own metrics. However, we plan to use it across all platforms eventually.

cmd/k8s-operator,k8s-operator/sessionrecording: ensure recording header contains terminal size for terminal sessions (#12965)
* cmd/k8s-operator,k8s-operator/sessonrecording: ensure CastHeader contains terminal size

For tsrecorder to be able to play session recordings, the recording's
CastHeader must have '.Width' and '.Height' fields set to non-zero.
Kubectl (or whoever is the client that initiates the 'kubectl exec'
session recording) sends the terminal dimensions in a resize message that
the API server proxy can intercept, however that races with the first server
message that we need to record.
This PR ensures we wait for the terminal dimensions to be processed from
the first resize message before any other data is sent, so that for all
sessions with terminal attached, the header of the session recording
contains the terminal dimensions and the recording can be played by tsrecorder.
