WowCosIdAutoConfiguration

Gives the Wow host CosId's aggregate id generators when the application runs CosId (it has CosId's CosIdRuntime bean, which CosId's starter starts from cosid.*). This module lists it in META-INF/spring/org.springframework.boot.autoconfigure.AutoConfiguration.imports; its ordering (after CosId's auto-configuration, before the host's WowAutoConfiguration) is in META-INF/spring-autoconfigure-metadata.properties, so that it imports no Spring Boot type.

CosIdAggregateIdGenerator is the host's wowAggregateIdGenerator, unless the application has a bean of that name: the generator of every aggregate type that wow.aggregates.*.id-generator does not name, CosId's generator named after the aggregate, else wow.cosid.aggregate-generator. As an me.ahoo.wow.spi.id.AggregateIdGeneratorSource it lets id-generator name CosId's generators. The node's own ids stay the host's (UUIDv7): a CosId id is unique only within its namespace, and request ids from several services meet in one context's idempotency key.
