/**
* CFN Loop Orchestrator - Unified CFN Loop Coordination
*
* Integrates all CFN loop components into a single orchestration layer:
* - ConfidenceScoreCollector (parallel collection)
* - IterationTracker (Loop 2/3 management)
* - FeedbackInjectionSystem (failure handling)
* - CFNCircuitBreaker (timeout and fault tolerance)
* - SwarmMemory (coordination and persistence)
*
* Orchestrates complete workflow:
* 1. Initialize swarm
* 2. Execute Loop 3 (primary swarm with iterations)
* 3. Collect confidence scores (≥75% gate)
* 4. Execute Loop 2 (consensus with Byzantine voting)
* 5. Process results or inject feedback
* 6. Handle escalation
