fix(lock): fence write commit on lock loss (backlog#899 Phase 2) Phase 0+1 (#4388) made object write locks refreshable and marks the guard lost when the heartbeat can no longer refresh a quorum, but does not act on it. Under a partition a long write's lock can expire on an unreachable node and be reclaimed, letting a third party re-acquire it; the original writer keeps going and both commit -- a double write. Expose the loss signal through NamespaceLockGuard::is_lock_lost() and ObjectLockDiagGuard::is_lock_lost(), and fence the commit in put_object and complete_multipart_upload: immediately before rename_data (the atomic commit point), abort with a retryable NamespaceLockQuorumUnavailable (503) if the lock was lost. In multipart the check precedes cleanup_multipart_path so a lost lock leaves the upload intact and retryable. A write that already reached rename_data Ok is durable and never aborted. The loss criterion is unchanged (reacts to Phase 1's signal). Heal and the long-GET read side are deferred follow-ups.
