/**
 * Observability Module - Unified tracing, logging, and metrics
 *
 * Supports 14+ observability integrations:
 * - Langfuse, LangSmith, LangWatch
 * - Arize AX, Axiom, Braintrust
 * - Helicone, Laminar, Maxim
 * - Patronus, Scorecard, SigNoz
 * - Traceloop, Weave
 *
 * @example Basic usage
 * ```typescript
 * import { createObservabilityAdapter, setObservabilityAdapter } from 'praisonai';
 *
 * // Enable observability
 * const adapter = await createObservabilityAdapter('langfuse');
 * setObservabilityAdapter(adapter);
 *
 * // Use with agents
 * const agent = new Agent({
 *   instructions: "You are helpful"
 * });
 * ```
