A leader-only runnable checks every configured provider concurrently
under one timeout per round (first round at start, then every interval),
keeps the latest results for the metrics collector, logs targets going
down, changing reason or coming back, and publishes one ProviderHealth
object per provider: created with a managed-by label when missing, then
a status merge patch. Per-target lastTransitionTime survives rounds in
which ready does not flip. Objects of providers that are no longer
configured are deleted once at start; with checks turned off, all are.
Reads go through the API reader, so no cluster-wide informer is needed.

Each configured host is checked concurrently over the pooled SSH+libvirt
connection: libvirt version and hostname prove the daemon answers, then
the configured pool must exist and be running, with its free space
reported. Dial failures are now tagged with their stage (SSH material,
TCP, SSH handshake, libvirt connect) by a dialError that keeps the
message and unwraps to the cause, so classification is unchanged and the
check can say why a host is unreachable. A pool verdict is decided after
the call returns so it never drops a working connection.

Checker is an optional interface next to Provider: Check returns one
verdict per target and never fails as a whole. The kubernetes provider
lists at most one managed Pod cluster-wide (the verb and scope GC relies
on); the GCP provider fetches a single page of at most one managed
instance through a new Probe seam method, since the SDK treats
MaxResults as a page size and the existing AggregatedList drains every
page.

One operator-owned object per configured provider will carry the
periodic check result: a Ready condition, per-target verdicts with their
own transition times, and a ready/total count for kubectl get. There is
no spec; only a viewer role is shipped since the operator is the sole
writer. Written by hand (kubebuilder is not installed), registered in
the existing AddKnownTypes call rather than a second init().
