Code Review

This pull request significantly enhances the schematics migration capabilities by introducing a new data model and logic for pattern-based replacements, splitting input properties, and adding default attributes when renaming elements. The changes are extensive, well-structured, and include comprehensive tests for the new functionality. Overall, this is a great addition. I've identified one potential bug in the new pattern replacement logic and a minor maintainability improvement, which are detailed in the comments.
