build-release.sh deleted every png/jpg in the staged tree except under
frontend/dist. That emptied frontend/src/assets/extension-icons in the
shipped /opt/serverkit, so the tree could no longer rebuild its own
frontend: ExtensionIcons.js imports 18 of those files and any `npm run
build` from the release (which `serverkit doctor --fix` triggered through
the Dockerfile) died on unresolved imports. Leave the whole frontend/ tree
alone; the tar excludes already keep docs and dev screenshots out.
Guarded in test_release_workflow.sh.
