BackupRunner.BackupWithSnapshotHook tails the task log for the 'create storage snapshot' marker (snapshot mode only) and fires onSnapshot once; localapi flips /backup/status to 'snapshotted' before 'done' so the controller resumes early. Phase 0 validated on PVE 9.2.2: marker confirmed, downtime ~24s->~1s (934MB). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
