C6b: IAlarmWatchListResolver.ResolveAsync doc now notes that while discovery being
unavailable never throws, a triggered cancellation token still propagates.
C7: annotate the original design doc where it drifted from the shipped code — metric
names / unimplemented watch-list gauges, and the proto-type location (gateway proto, not
worker proto).
Auto-failover/failback between the wnwrap alarmmgr consumer and a new
worker-side SubtagAlarmConsumer that advises alarm subtags and synthesizes
transitions. GR-SQL+config watch-list discovery, ack via ack-comment write,
degraded state surfaced in the gRPC contract and dashboard/metrics.
