Which issue does this PR close?
Rationale for this change
The list files cache currently performs a full table listing on a cold cache miss, even when partition pruning has already narrowed the scan to a specific path prefix.
This makes selective partition queries pay the cost of listing the full table unless users disable the cache.
What changes are included in this PR?
Are these changes tested?
Yes
Are there any user-facing changes?
Partition-pruned listing table queries with the list files cache enabled avoid full table listings on cold cache misses.
