* fix(s3): list empty directories as directory markers A real but empty directory created out of band (mount, mkdir, filer API) carries no MIME, so it was hidden from S3 listings. hadoop-aws getFileStatus probes LIST prefix=dir/ &delimiter=/ and reads an empty result as a missing path, which breaks Spark's eventLog.dir when it points at an empty directory. Surface such directories as directory markers, matching directories created via PutObject with a trailing "/". Emptiness comes from the recursion result, and the marker MIME is set only on the in-memory listing entry, so empty directories stay eligible for empty-folder cleanup. * fix(s3): only surface empty directory markers for explicit dir probes Restrict the empty-directory marker to a trailing-slash prefix probe (prefix=dir/), the pattern hadoop-aws getFileStatus uses. Plain listings are left as before, so an empty directory left behind by deleted objects (e.g. after lifecycle expiration) is no longer shown as a phantom key.
