Pull request overview

This PR refactors the layout transformation system by replacing the abstract test implementation with a concrete PointwiseConcatTransform implementation and comprehensive tests. The changes introduce better error handling through typed return values and add support for field-to-column mapping via an IndexMap structure.

Key Changes:

• Introduces PointwiseConcatTransform class that concatenates tensor fields into a single matrix for ML model input
• Updates LayoutTransform interface to return AMSExpected<IndexMap> from pack() and AMSStatus from unpack() for better error handling
• Adds comprehensive test coverage with 8 test cases covering both success scenarios and error conditions

LGTM. The concept of LayoutTransform and IndexMap is good but will require exhaustive documentation with examples.

Thank you. I am planning to add more documentation. I will start doing it after I get an end to end example working with this. I am also suspecting I have bugs in my overall logic. So I need this end-to-end example to fix/simplify components.
