/**
 * Generic Metrics Library
 *
 * A portable, framework-agnostic metrics collection system.
 * Tracks performance, latency, and usage metrics for agents, tools, and requests.
 *
 * Features:
 * - In-memory metrics storage (fast access)
 * - Optional persistence backend (PostgreSQL, MongoDB, Redis, etc.)
 * - Configurable logging
 * - Generic context IDs (works with any domain)
 * - Type-safe metrics
 *
 * Usage:
 * ```typescript
 * import { metricsCollector, MetricsPersistence } from 'llm-metrics';
 *
 * // Configure persistence (optional)
 * class MyPersistence implements MetricsPersistence { ... }
 * metricsCollector.setPersistence(new MyPersistence());
 *
 * // Configure logger (optional)
 * metricsCollector.setLogger(myLogger);
 *
 * // Record metrics
 * metricsCollector.recordAgent({ ... });
 * ```
