- Add TypeName method to handle pg_catalog prefix for JSON types
- Implement VALUES context detection to exclude JSON types in VALUES clauses
- Fix List method to properly propagate transformation context
- Add context helper methods for different transformation scenarios
- Update version number to 170004 for PG17 compatibility
