Module retention 

Retention and garbage-collection for the unified session store.

Structs

gc_legacy

Remove the legacy history/ and logs/ directories after they have been imported into the unified store by crate::migrate_legacy.

pin_session_retention

Write a retention pin for a session (best-effort path check by caller).
