Python-Rust bridge for plugin execution

This bridge provides a minimal, focused interface for:

1. Loading plugin package metadata via entry points
2. Executing plugins with configuration

Plugin discovery uses AST-based analysis instead of runtime inspection, making it more efficient and reducing Python interpreter overhead.

PYTHONHOME Configuration

PYTHONHOME is resolved from the venv’s pyvenv.cfg file to ensure compatibility with PyO3 (which is linked at build time). This avoids version mismatches between the discovered Python and the compiled binary.
