/**
* E2E Test Suite for Complete Batch API Workflows
* Tests end-to-end workflows for content generation and embeddings
*
* Prerequisites:
* - GEMINI_API_KEY environment variable set
* - npm run build (compiled server)
*
* Usage:
* node tests/batch-api-workflows-test.mjs
*
* Note: These tests involve actual API calls and may take time
