/**
* electron-builder afterPack hook.
*
* The Python backend is a PyInstaller onedir bundle shipped via extraResources
* into Contents/Resources/backend/. electron-builder's deep signing does NOT
* cover extraResources, so its executable + hundreds of .so/.dylib files stay
* unsigned — which makes notarization reject the whole app.
*
* This hook runs before electron-builder signs the .app: it code-signs every
* Mach-O file under the backend dir with hardened runtime + entitlements, so
* the outer app signature and notarization succeed.
