The local-dev import path was adding sdk/python/ to sys.path, but the
molecule_agent package lives at the repo root, not under sdk/python/.
The dead-code path silently failed (isdir check returned False) so the
script only worked when molecule-ai-sdk was pip-installed. Now uses
os.path.normpath(.. / ..) pointing to the repo root instead.
