It reads the keeper's status from its own state asked, what the keeper holds,
and how many accepted verdicts wait on its consumer <node>_nats_keeper on
EVENTS from the monitoring endpoint, and answers HealthOf's judgement:
unhealthy, naming why, past the three-minute bound; the entries refused,
waiting and past the raise mark named beside.

nats-tools keep is the process keeper, on its own account (own secret
broker-keeper): it asks the indexer's indexer_bus_state once, on a backoff
from 10 s doubling to 5 min while it does not answer (unhealthy meanwhile,
nothing created or orphaned), then binds its durable consumer on EVENTS
(<node>_nats_keeper, the indexer's manifest-accepted) and applies each verdict
only if newer by the indexer's revision; a manifest-accepted carrying no
revision yet is read as 0. A fill pass every minute, waiting entries made
again on the same backoff. It says its events on its own stream and its
conditions through the condition keeper, and serves nothing (ADR 0436 §3).
