/**
 * auto-api-observe
 * ─────────────────────────────────────────────────────────────────────────────
 * Zero-config observability for Node.js APIs — request tracing, DB profiling,
 * slow-request detection, distributed trace IDs, and structured JSON logs.
 * Ships telemetry to apilens.rest when an apiKey is provided.
 *
 * Supported frameworks: Express · Fastify · Koa · Hono · NestJS · Next.js ·
 *   Hapi · Elysia · Apollo Server · AWS Lambda · tRPC · Restify
 *
 * @example Express
 * ```js
 * const { observe } = require('auto-api-observe');
 * app.use(observe({ apiKey: process.env.APILENS_KEY }));
 * ```
 *
 * @example Fastify
 * ```js
 * const { fastifyObservability } = require('auto-api-observe');
 * await fastify.register(fastifyObservability, { apiKey: process.env.APILENS_KEY });
 * ```
