## Summary Fixes the JS SDK CLI push bundle path so uploaded function bundles inline Braintrust SDK packages by default again. The regression came from passing `plugins: []` into `buildOpts()`, which still allowed the built-in known-package externalization plugin to mark `braintrust`, `autoevals`, and `@braintrust/*` external. Hosted function runtime then failed at load time with `Cannot find module 'braintrust'`. This change disables only that known-package externalization plugin for final uploaded bundles, while keeping it enabled for local discovery builds. ## Testing - `cd js && pnpm vitest src/cli/auto-instrumentation.test.ts src/cli/util/external-packages-plugin.test.ts` - `./node_modules/.bin/prettier --write js/src/cli/index.ts js/src/cli/auto-instrumentation.test.ts`
