Paulo Lieuthier 1c607dc1d3 feat: implement add_extension in Python binding (#596) ...

Add support for registering custom Python functions as Rego extensions,
allowing users to call Python callables directly from Rego policies.

The implementation:
- Converts Rego values to Python types on call, and back on return
- Validates that the extension is callable at registration time
- Wraps errors with the extension name for easier debugging
- Documents clone semantics (shared callable reference across clones)

Tests cover: basic execution, type conversions (int, float, bool, None,
list, dict, set), zero-arg extensions, wrong arity, exception
propagation, non-callable rejection, and duplicate registration.
