   ### Search before asking
   
   - [x] I searched in the [issues](https://github.com/apache/fluss/issues) and found nothing similar.
   
   
   ### Description
   
   getNullCounts() currently returns Long[]. Since null counts are stored as 4-byte integers in the batch statistics format, int[] is sufficient and avoids boxing overhead (8 bytes per Long vs 4 bytes per int). Use -1 as the sentinel for "not available". This reduces memory for cachedNullCounts and statsNullCounts, especially for wide tables (1000+ fields).
