fix: restore and improve RangeFunction, RangeTableSample, and XmlSerialize transformation methods

- Restored stashed improvements to RangeFunction, RangeTableSample, and XmlSerialize methods
- Continued systematic node wrapping improvements following v13-to-v14 patterns
- Maintained 178/258 test pass rate (69.0% success rate) locally
- Fixed transformation logic to properly handle nested properties and arrays
- Ensured all methods follow proper result object creation and node wrapping
