Pull request overview
This PR adds comprehensive support for statement diffing to the Spirit project. It introduces a new Diff() method that compares two CREATE TABLE statements and generates the necessary ALTER TABLE statement to transform one into the other. The implementation is part of the statement API which can be used independently before calling spirit.
Changes:
- Added a complete diff implementation with support for columns, indexes, constraints, table options, and partitioning
- Enhanced the parser to capture more detailed schema information (partition expressions, index column details, foreign key actions)
- Added extensive test coverage with 985 lines of table-driven tests covering various schema migration scenarios

This adds support for statement diffing. It is not used by Spirit internally, but is part of the statement API which can be used before calling spirit.
