Related to #47711 Enable Go pointer struct fields (*string, *int32, etc.) to represent nullable columns in the row-based data processing path. A nil pointer maps to a NULL value in Milvus; a non-nil pointer dereferences to the actual value. Changes: - ParseSchema: pointer fields auto-infer Nullable=true (PK excluded) - AnyToColumns: use reflect.Value.IsNil() to call AppendNull for nil pointers, Elem().Interface() for non-nil — bypasses Go's typed-nil problem where (*T)(nil) as interface{} is != nil - SetField: wrap/unwrap pointer values during field assignment - fillData/fillPKEntry: check IsNull() on columns and set nil pointers for null values, wrap non-null values in reflect.New pointers - Dynamic field path: same nil/deref logic for pointer fields going into the JSON dynamic column Signed-off-by: Congqi Xia <congqi.xia@zilliz.com>
