/**
 * @module @dagengine/core
 *
 * Core engine for orchestrating AI-powered workflows with dependency management.
 *
 * @example Basic Usage
 * ```typescript
 * import { DagEngine } from '@dagengine/core';
 *
 * const engine = new DagEngine({
 *   plugin: myPlugin,
 *   providers: myAdapter,
 *   execution: {
 *     concurrency: 10,
 *     timeout: 30000
 *   }
 * });
 *
 * const result = await engine.process(sections);
 * ```
 *
 * @example With Pricing
 * ```typescript
 * const engine = new DagEngine({
 *   plugin: myPlugin,
 *   providers: myAdapter,
 *   pricing: {
 *     models: {
 *       'gpt-4': { inputPer1M: 30, outputPer1M: 60 }
 *     }
 *   }
 * });
 *
 * const result = await engine.process(sections);
 * console.log(result.costs?.totalCost);
 * ```
