feat(health): add status display for DaemonSet and StatefulSet (#32)

Introduce extendedCarp struct to capture numeric status fields
(desiredNumberScheduled, numberReady, replicas, readyReplicas, etc.)
that are lost during standard Carp unmarshaling. Synthesize an
"Available" condition from these fields so EnhanceStatus can
determine health correctly.

Closes #32
