AggregateContainer
Aggregates multiple PSR-11 containers and delegates resolution requests among them.
This container implementation respects PSR-11 expectations and throws a NotFoundException when a requested service cannot be found in any delegated container.
It caches resolved entries to prevent redundant calls to delegated containers.
