Bug: sys_transform_entry with use_source_script=false is transformed as scripted mapping

Summary

When transforming a sys_transform_map that has descendant sys_transform_entry records, the SDK appears to treat a direct field mapping as a scripted mapping if the entry contains the platform default placeholder source_script, even when use_source_script is explicitly false.

This changes runtime behavior from copying source_field to target_field into running a placeholder script that returns an empty string.
