/**
* CFN Loop Orchestrator - TypeScript Implementation
*
* Orchestrates the complete CFN (Complete Fail Never) Loop workflow:
* 1. Loop 3: Spawn implementation agents
* 2. Gate Check: Validate test pass rates against threshold
* 3. Loop 2: Spawn validator agents if gate passes
* 4. Consensus Check: Validate consensus among validators
* 5. Product Owner Decision: PROCEED/ITERATE/ABORT
*
* Features:
* - Type-safe state management
* - Redis coordination for agent communication
* - Iteration management with max bounds
* - Comprehensive error handling
* - Full audit trail via state tracking
*
* @module orchestrator
