fix: disable fallback upload mechanism that was deleting large files

The fallback was being triggered and removing all JS files >100KB,
which corrupted the main bundle. Changes:

- Disabled fallback upload completely (if: false)
- Set main upload to fail properly (continue-on-error: false)
- Increased memory limit to 8GB for main upload
- This ensures the complete 1.6MB bundle is uploaded intact
