test: verify all workflow examples use real LLM models

Completed comprehensive testing of all 5 workflow examples to confirm
they use real LLM integration with Ollama (llama3.2:3b) rather than
hardcoded responses:

✅ 1-prompt-chaining: Multi-step development workflow with role-based agents
✅ 2-routing: Task complexity analysis and model selection
✅ 3-parallelization: Multi-perspective parallel analysis with unique outputs
✅ 4-orchestrator-workers: Hierarchical task decomposition and worker coordination
✅ 5-evaluator-optimizer: Iterative content generation with quality metrics

Key evidence of real LLM usage:
- Unique workflow IDs for each execution
- Context-aware responses matching specific prompts
- Dynamic quality metrics and confidence scores
- Progressive workflow state transitions
- Distinct perspective-based outputs with varying confidence levels

All workflows successfully demonstrate proper prompt and context passing
to Ollama LLM models, confirming no hardcoded response patterns.
