[Feature Request]: Native CPython Integration in Apache Hop (No Extension Required)

### What would you like to happen?

I would like to explore the possibility of natively integrating CPython into Apache Hop so that users don’t need to install an additional extension. Python is widely used for data transformation, automation, and scripting, and having CPython built into Hop by default could greatly enhance its flexibility.

### Issue Priority

Priority: 3

### Issue Component

Component: Transforms

Start by reviewing Apache Hop's Transforms component and the current boundary between Hop and its Python extension. Define the CPython integration requirements, packaging and runtime implications, and the user-facing behavior that would demonstrate the feature is complete.
