fix: correct v16-to-v17 version number and wrap all node transformation methods

- Fix ParseResult version from 160000 to 170000 (PG17)
- Systematically wrap ~150+ node transformation methods to return { NodeType: node }
- Resolves critical CI failure in parser-tests check
- Ensures AST structure consistency across v16-to-v17 transformations
