Fix overly broad AlterTableCmd Integer transformation

- Restrict AlterTableCmd transformation to SET STATISTICS operations only
- Prevent over-transformation of CHECK constraint values like 'price > 0'
- Follow v14-to-v15 transformer pattern for specific context handling
- Should resolve CI failures from 97 down to expected ~67 range

The pretty-constraints.test.ts now passes locally, confirming the fix works.
