Summary

Raises tiny-blocks/building-blocks to ^6.0. In 6.0, DomainEvent gains occurredAt(): ?Utc and the record's occurrence timestamp is resolved from the explicit argument to EventRecord::from(), then the event's own occurredAt(), then the current moment. The outbox copies occurred_at from that record and never reads the clock, so no source change is needed. The README now states where occurred_at comes from.

Breaking for consumers, released as 6.0.0: it requires tiny-blocks/building-blocks 6.0, whose DomainEvent implementations that do not use DomainEventBehavior must add occurredAt().
