Review Comment:
Style nit, a bit more concise:
```suggestion
if field.metadata:
# Try Parquet field ID first
if field_id_bytes :=
field.metadata.get(PYARROW_PARQUET_FIELD_ID_KEY):
return int(field_id_bytes.decode())
# Fallback: try ORC field ID
if field_id_bytes := field.metadata.get(ORC_FIELD_ID_KEY):
return int(field_id_bytes.decode())
```
