fix: add Integer transformation method to V14ToV15Transformer

- Add direct Integer node transformation to handle cases where Integer nodes
  are not wrapped in A_Const (e.g., in CREATE AGGREGATE statements)
- Transform Integer nodes with ival=-1, ival=0, or undefined ival to empty {}
- Fixes cascading transformation failures in V14→V15 chain
- Maintains compatibility with existing PG13→PG14 improvements
- Resolves 'original-define' test failures in both 13-14 and 14-15 suites
