/**
 * Consumer fixture for .github/workflows/test-package-pack.yml. Runs against
 * the packed tarball with only non-optional peers installed, so any import
 * that transitively pulls an optional peer fails at module load.
 *
 * Subpaths deliberately NOT imported because they require optional peers:
 *   models/{anthropic,openai,google,vercel}, a2a, a2a/express,
 *   session/s3-storage, telemetry. Those are covered by the sibling
 *   `../esm-module` and `../cjs-module` suites.
