/**
 * Agentic QE v3 - LLM Provider System
 * ADR-011: Multi-provider LLM support for Quality Engineering
 *
 * This module provides a unified interface for working with multiple LLM providers:
 * - Claude (Anthropic) - Primary provider
 * - OpenAI (GPT-4) - Secondary provider
 * - Ollama (Local) - Zero-cost local development
 *
 * Features:
 * - Round-robin and cost-based load balancing
 * - Circuit breaker for resilience
 * - LRU caching for repeated queries
 * - Cost tracking and limits
 * - Automatic failover
 *
 * @example
 * ```typescript
 * import { createProviderManager, createQEProviderManager } from '@agentic-qe/v3/shared/llm';
 *
 * // Create a provider manager
 * const manager = createQEProviderManager();
 * await manager.initialize();
 *
 * // Generate text
 * const response = await manager.generate('Write a test for UserService', {
 *   systemPrompt: 'You are a QE assistant...',
 *   maxTokens: 2048,
 * });
 *
 * // Generate embedding
 * const embedding = await manager.embed('test coverage analysis');
 *
 * // Code completion
 * const completion = await manager.complete('function calculateTotal(');
 *
 * // Check health
 * const health = await manager.healthCheck();
 *
 * // Get cost summary
 * const costs = manager.getCostSummary('day');
 * ```
