`node_health` fires once at the transition, while `HEALTH_FLOOR` still
hides the node, and nothing is published when the floor expires 60 s
later. Schedule a per-node re-read for that moment, cancelled when the
node recovers and on socket teardown. Health now also invalidates the
brain graph, whose key is a sibling of the flow's rather than a child,
so Home's fault rings never moved on a health flip at all.
