fix: remove overly broad JSON pg_catalog prefix logic from TypeCast method

- Simplified TypeCast method to basic pass-through transformation
- Removed context-insensitive JSON prefix addition that was causing test failures
- Current status: 249/258 tests passing (9 failures remaining)
- Need targeted approach for JSON prefix logic based on specific contexts
