WARNING: Deferred repairs are not counted in the summary

When repairClaimedDailyUsageRollup returns false (claim lost / advisory lock contended), the row is requeued via failDailyUsageRollupRepair, but it is not added to summary.failed. Callers that assume claimed === repaired + failed.length will silently undercount outstanding/backlogged repairs (e.g. { claimed: 5, repaired: 3, failed: [] } while 2 rows were actually deferred). Consider recording deferred rows in the summary as well so monitoring/alerting reflects the true outstanding backlog.
