Review Comment:
> It looks like these weren't left out due to an oversight but rather they
were intentionally excluded. I'm curious if there is any background on why that
is -- is there some specific pitfall related to cleaning up the partition stats?
Good catch — to the best of my knowledge, Polaris `drop table prune`
currently has a gap compared to Iceberg's implementation due to some reasons
(which I don't know either, curious too)
Iceberg will delete all file types under the metadata/ directory, including
manifests, manifest lists, metadata files, previous metadata, and .stats files
(both table and partition-level). Iceberg code pointer:
[CatalogUtil.java#L124](https://github.com/apache/iceberg/blob/main/core/src/main/java/org/apache/iceberg/CatalogUtil.java#L124)
for reference.
This gap also discussed earlier in [this issue
comment](https://github.com/apache/polaris/issues/289#issuecomment-2347423467).
