GlobalIdGenerator

Generates the message-level ids of a node: command ids, the request id of a request that names none, wait ids, and Ids.next of domain code. UUIDv7 by default, or the application's own; wow-cosid gives aggregate ids alone (AggregateIdGenerator), never these, since request ids from several services meet in one context's idempotency key and a CosId id is unique only within its namespace.
