App bundle configuration missing

The AAB lacks BundleConfig.pb. Final structure verification fails.

#Common causes

• An archive was assembled as a ZIP instead of a complete bundletool output, or repackaging removed the configuration.

#Fixes

• Regenerate the AAB through the exporter's bundletool build-bundle step and retain BundleConfig.pb when normalizing/signing the archive.
