   Thanks for the suggestion @sunchao!
   
   I've updated the PR to support `arrays_zip` with duplicate field names 
natively in Comet instead of falling back to Spark:
   
   1. **Serde update**: Removed the duplicate field names check in 
`CometArraysZip.getSupportLevel`.
   2. **Native Rust & SQL tests**: Confirmed Arrow `StructArray` handles 
duplicate field names without issue. Updated the `arrays_zip.sql` tests to 
assert native Comet execution for queries like `arrays_zip(a, a)` and added a 
unit test in `native/spark-expr`.
   
   Ready for another look when you get a chance!
