Crate fidius_python 

Python plugin runtime for Fidius.

This crate embeds CPython into the host process via PyO3 and (in later tasks) exposes a PluginHandle whose dispatcher calls into a loaded Python module. Hosts opt into Python plugin support by depending on this crate (typically through fidius-host’s python feature flag).

At this stage the crate provides only the foundation: shared interpreter initialisation and Python-exception-to-PluginError conversion. The loader, dispatcher, and packaging integration land in subsequent tasks under FIDIUS-I-0020.
