Apply ML traits framework to four core agents for automatic optimization.
1. **CoordinatorAgent** - ML Worker Selection
- Learns optimal worker routing (30-40% improvement)
- Performance-based load balancing
- Automatic specialization discovery
2. **TreeOfThoughtsAgent** - Strategy & Parameter Learning
- Learns search strategy (BFS/DFS/Best-First)
- Optimizes branch_count and max_depth (20-30% faster)
- Task-adaptive exploration
3. **ReflectionAgent** - Adaptive Refinement
- Learns refinement count and quality threshold
- Diminishing returns detection (15-25% cost savings)
- Automatic early stopping
4. **RAGAgent** - Retrieval Optimization
- Learns optimal topK per query type
- Complexity-based adaptation (10-20% relevance gain)
- Source quality tracking
