MINOR-3: new DriverHostActorPrimaryRoleSourceTests case drives the
deny flip with a real ClusterEvent.MemberUp on the EventStream (how the
cluster's domain-event publisher reaches a Cluster.Subscribe subscriber)
instead of a direct RepublishPrimaryVerdict tell; it fails when the
Cluster.Subscribe(IMemberEvent) call is deleted.
MINOR-2: the published verdict MIRRORS the live gate; before this node has
joined its member count is 0 and both allow (seconds; up to the bootstrap
guard's 25 s probe), so the Sparkplug primary-host claim can be held on
both nodes in that window (native ack is unaffected - view and route
agree). Behaviour deliberately unchanged: denying until self is Up would
change the live gate too and delay writes/acks on a single-node cluster's
own join. Comments + AlarmTracking.md / Redundancy.md / Mqtt.md corrected.

Review R1:
- M1 (#609): DriverHostActor.StopChild releases the instance's resilience state before evicting the hub.
- m2 (#597): DriverHostActor publishes ShouldServiceAsPrimary() to IDriverPrimaryRoleSource at start and on
cluster membership changes (deduped), so the native-ack gate denies in a pair's boot window.
- m4 (#601): ApplyCachedArtifact returns false on empty/malformed bytes; the cached revision is not adopted,
Direct mode goes Stale (no RUNNING FROM CACHE), FetchAndCache lands Steady-with-no-revision and a
re-dispatch of the same revision really applies.
- m3 (#603): LocalDbReplicationPolicy splits into CapturesChanges (PeerAddress||ApiKey, registration) and
SharesRowsWithPeer (ApiKey && (PeerAddress||SyncListenPort>0), alarm drain gate).
- m5 (#618): Program.cs catch-all filters HostAbortedException (design-time tooling).
- m6 (Cluster-002): ClusterRoleInfo seeds only Up/WeaklyUp members.
