Teknium aa8ceed4b6 fix(memory): keep a stale holder's late close() from evicting a fresh registry entry
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.
