* feat(dns): implement extra dns names for machine in m.internal
This implements <machinename>.m.internal and <machineid>.m.internal as
names that can be queried in the cluster.
Listing all machines/services is not implemented, this may come later.
Fixes: #340

* Implement getting all machine address
A query for m.internal returns all ip address
There is no overflow check

* fix(store): debounce container change notifications to avoid reconcile storms
SubscribeContainers forwarded every raw row-level change event from
Corrosion as its own signal, with no coalescing. Each signal triggers
a full reconcile (ListContainers + regenerate) in every independent
subscriber (caddy-controller, DNS resolver) on every machine in the
cluster. With enough container/health-check churn across services,
this produces a sustained stream of events (observed ~1.6-1.7/sec
cluster-wide on a 45-service, 7-machine cluster) and burns meaningful
CPU on every machine continuously, regardless of whether that machine
runs Caddy locally. On a resource-constrained node this escalated into
kernel RCU stall warnings and a full freeze.
Coalesce bursts of events into a single signal per debounce window
instead of forwarding one per event.
* bound debounced changes by the window

* feat: add uc dns set
This allows manual setting of the cluster's domain name. I use this to
make the local cluster admin aware that this has been done.
(and then manually update the external dns)
```
% uc dns set ctrl.u.science.ru.nl
Set cluster domain: ctrl.u.science.ru.nl
Deploy the Caddy reverse proxy service ('uc caddy deploy') to enable internet access to your services via the reserved or your custom domain.
% uc dns show
ctrl.u.science.ru.nl
% uc dns set ctrl.u.science.ru.nl
Error: domain already reserved
% uc dns release
Released cluster domain: ctrl.u.science.ru.nl
```

This can be useful to leave a container running without specifying a
command like `sleep`, and probably in other situations as well.
