Apply the confirmed retention policy to duplicate entries.
A store for existing matching content and category returns the existing ID without updating expires_at. If an existing Environment entry has a 7-day expiry, then the user confirms a later permanent: true store, this path reports success but the entry still expires. Update the duplicate path to apply the confirmed TTL or report the existing expiry before confirmation. Add a regression test for an expiring entry followed by a permanent store.

Prevent substring matches from overriding a preference.
After Environment takes precedence, categorize_fact("I always use keyboard shortcuts") returns MemoryCategory::Environment because keyboard contains key. auto_retain_memory then assigns the Environment TTL instead of retaining this Preference permanently. Match environment indicators as tokens or validated phrases. Add this case to the regression test.
