 * darwin-langgraph — LangGraph.js adapter for darwin-agents.
 *
 * Public entry. 11 surfaces + re-exported types + error classes.
 *
 * @example
 * ```ts
 * import { StateGraph } from "@langchain/langgraph";
 * import { defineAgent } from "darwin-agents";
 * import {
 *   createDarwinNode,
 *   darwinAnnotation,
 *   withDarwinEvolution,
 * } from "darwin-langgraph";
 *
 * const researcher = defineAgent({
 *   name: "researcher",
 *   role: "Topic Researcher",
 *   description: "Five bullets on a topic.",
 *   systemPrompt: "Return exactly 5 bullet points.",
 * });
 *
 * const graph = withDarwinEvolution(
 *   new StateGraph(darwinAnnotation())
 *     .addNode("research", createDarwinNode(researcher))
 *     .addEdge("__start__", "research")
 *     .compile(),
 *   {
 *     nodeMap: { research: "researcher" },
 *     onTrajectory: (event) => {
 *       console.log(`${event.nodeName} (${event.agentName}) trajectory:`, event.trajectory);
 *     },
 *   },
 * );
 *
 * const result = await graph.invoke({ task: "What is GEPA?" });
 * console.log(result.output);
