Now the code generator supports specifying a custom output directory and extension/name template for generated DI files via build.yaml ( and ). This allows placing all generated code in custom folders and using flexible naming schemes. docs: update all user docs and tutorials to explain new output_dir/build_extensions config - Added detailed usage and YAML examples to cherrypick_generator/README.md - Synced full_tutorial_en.md and full_tutorial_ru.md (advanced codegen section) with explanation of new configuration and impact on imports - Updated quick_start_en.md and quick_start_ru.md to mention advanced customization and point to tutorials - Added troubleshooting and tips for custom output/imports in docs
