Module delivery 

Track pending consumer deliveries for resolver implementations.

Resolvers often need the same delivery lifecycle: keep a fetch alive while Consumer::deliver validates a response, abort that validation if the fetch is pruned, and reuse a cached response for subscribers that were added while validation was in progress. This module owns that lifecycle without making assumptions about how data is fetched.
