Module session 

Sessions and reusable session pools. Sessions and the session pool.

Expiry uses a persisted wall-clock timestamp instead of an Instant, so restarting a crawler cannot silently renew sessions. Persistence is explicit rather than AutoSaved: the live cookie jar remains authoritative instead of being duplicated behind another lock. Pools are created before crawler storage is available, so SessionPool::attach_persistence bridges that lifecycle gap instead of requiring storage in SessionPool::new.
