Test Phase 3.2: LLM Mode Integration

Tests the new generic run_optimization.py with --llm flag support.

This test verifies:
1. Natural language request parsing with LLM
2. Workflow generation (engineering features, calculations, hooks)
3. Integration with LLMOptimizationRunner
4. Argument parsing and validation
