- tailscale client gets a new AuthUrl and sets entry in the regcache
- regcache entry expires
- client doesn't know about that
- client always polls followup request а gets error
When user clicks "Login" in the app (after cache expiry), they visit
invalid URL and get "node not found in registration cache". Some clients
on Windows for e.g. can't get a new AuthUrl without restart the app.
To fix that we can issue a new reg id and return user a new valid
AuthUrl.
RegisterNode is refactored to be created with NewRegisterNode() to
autocreate channel and other stuff.
When the node notifier was replaced with batcher, we removed
its closing, but forgot to add the batchers so it was never
stopping node connections and waiting forever.
Fixes#2751

The UserInfo endpoint is always queried since 5d8a2c2.
This allows to use all OIDC related features without any extra
configuration on Authelia.
For Keycloak, its sufficient to add the groups mapper to the userinfo
endpoint.
the client will send a lot of fields as `nil` if they have
not changed. NetInfo, which is inside Hostinfo, is one of those
fields and we often would override the whole hostinfo meaning that
we would remove netinfo if it hadnt changed.

Initial work on a nodestore which stores all of the nodes
and their relations in memory with relationship for peers
precalculated.
It is a copy-on-write structure, replacing the "snapshot"
when a change to the structure occurs. It is optimised for reads,
and while batches are not fast, they are grouped together
to do less of the expensive peer calculation if there are many
changes rapidly.
Writes will block until commited, while reads are never
blocked.

Before this patch, we would send a message to each "node stream"
that there is an update that needs to be turned into a mapresponse
and sent to a node.
Producing the mapresponse is a "costly" afair which means that while
a node was producing one, it might start blocking and creating full
queues from the poller and all the way up to where updates where sent.
This could cause updates to time out and being dropped as a bad node
going away or spending too time processing would cause all the other
nodes to not get any updates.
In addition, it contributed to "uncontrolled parallel processing" by
potentially doing too many expensive operations at the same time:
Each node stream is essentially a channel, meaning that if you have 30
nodes, we will try to process 30 map requests at the same time. If you
have 8 cpu cores, that will saturate all the cores immediately and cause
a lot of wasted switching between the processing.
Now, all the maps are processed by workers in the mapper, and the number
of workers are controlable. These would now be recommended to be a bit
less than number of CPU cores, allowing us to process them as fast as we
can, and then send them to the poll.
When the poll recieved the map, it is only responsible for taking it and
sending it to the node.
This might not directly improve the performance of Headscale, but it will
likely make the performance a lot more consistent. And I would argue the
design is a lot easier to reason about.

- Fix directory hierarchy flattening by using full paths instead of filepath.Base()
- Remove redundant container hostname prefixes from directory names
- Strip top-level directory from tar extraction to avoid nested structure
- Ensure parent directories exist before creating files
- Results in clean structure: control_logs/mapresponses/1-ts-client/file.json

Previously, nil regions were not properly handled. This change allows users to disable regions in DERPMaps.
Particularly useful to disable some official regions.
