We add plugins/css-module-stub.js to the jest package's assets.json to ensure it is copied into dist/packages/jest/plugins/ during the build. Without this, resolver.js could not locate the stub via require.resolve('./css-module-stub.js'), causing all CSS module imports in Jest tests to fail with "Cannot find module" errors. This fix aligns the asset configuration with the PR's intent of replacing identity-obj-proxy with the local stub.
