Follow-up to the #88347 salvage: after release_all_under() force-closes a profile's shared connection, a store re-created on the same path registers a fresh entry under the same key. A stale holder that later calls close() would pop that fresh entry (its refs were transferred nowhere), letting a third store open a second connection to the same database — exactly the multi-writer contention the shared registry exists to prevent. close() now evicts the registry entry only when it is still its own.
