ShardMapChanged

Defined in: src/cluster/ClusterEvents.ts:165
Shard ownership map recomputed. Published by every node’s region whenever the coordinator reallocates, so a listener sees the same map wherever it subscribes — the coordinator itself only runs on the leader.
Bursty by nature (a fresh cluster places every shard at once), so the
coordinator coalesces a burst into one broadcast; version counts
broadcasts, not individual assignments.
