* s3: keep transient object-entry errors out of ErrObjectNotFound getObjectEntry wrapped every fetch error as ErrObjectNotFound, so a transient filer failure (busy filer, ctx deadline, transport blip) was indistinguishable from a real miss. LifecycleDelete resolves ErrObjectNotFound permanently as NOOP_RESOLVED, so one flaky lookup at dispatch time silently skipped the object's expiration - errors=0, no retry, no log. This matches the flaky s3tests test_lifecyclev2_expiration signature: exactly one object of a same-rule pair surviving past its window. Only collapse genuine misses (filer not-found, version/latest-version sentinels); everything else propagates so the worker retries it as RETRY_LATER instead of resolving it. Also seed bucketConfigCache in the retention test server and teach the fake filer to inject per-path lookup errors. * s3: keep invalid version ids on the not-found path in getObjectEntry A malformed versionId used to collapse into ErrObjectNotFound like every other fetch error, so the handlers answered NoSuchKey. With transient errors now propagated, an invalid id would surface as InternalError; fold it back into the miss classification. * filer_pb: keep Unavailable out of LookupEntry's not-found normalization * s3: reject Unavailable in isObjectEntryMiss before message matching * s3: keep transient fallback errors out of latest-version resolution * filer_pb: limit LookupEntry's not-found text match to miss statuses * s3: limit isFilerNotFound text matching to miss statuses
