* fix(lock): isolate retry attempt lock ids
Generate a fresh lock id for each distributed lock retry attempt so late pending cleanup from an earlier attempt cannot release a lock acquired by a later retry.
Also add a regression test covering late-success cleanup versus retried acquisition.
* style(lock): normalize retry race regression test
Normalize the distributed lock retry race regression test formatting without changing behavior.
* test(lock): remove quorum-order assumption
Make the retry race regression test assert the safety property without assuming which delayed client enters the retry quorum first.
