   C++ already performs predicate-to-bucket conversion for 
`KeyValueFileStoreScan`, while this PR introduces a second append-specific path 
with different semantics. Java installs a shared total-aware selector for both 
scan types and computes the bucket using each manifest entry’s totalBucket. 
Could we centralize this in `FileStoreScan` and make the selector total-aware 
like java? Besides avoiding duplication, this would prevent the existing KV 
path from pruning historical files incorrectly after bucket rescaling. Thanks!
