Add JavaScript/TypeScript integration to LangChain documentation

[Copilot]

The LangChain documentation at genai-tools/langchain.html only covered Python integration. This extends it to include JavaScript/TypeScript support via @falkordb/langchain-ts.

Changes

genai-tools/langchain.md - Extended with JS/TS section:

• Added JavaScript/TypeScript Integration section with installation, quick start, key features, and API reference
• Reorganized existing Python content under explicit "Python Integration" heading
• Updated Resources section with npm package and GitHub repository links

Cross-references and navigation:

• Added bidirectional links between genai-tools/langchain.md and integration/langchain-js.md
• Updated genai-tools/index.md to indicate dual language support
• Added LangChain JS/TS entry to integration/index.md

Example Usage

import { FalkorDBGraph } from "@falkordb/langchain-ts";
import { ChatOpenAI } from "@langchain/openai";
import { GraphCypherQAChain } from "@langchain/community/chains/graph_qa/cypher";

const graph = await FalkorDBGraph.initialize({
  host: "localhost",
  port: 6379,
  graph: "movies"
});

const chain = GraphCypherQAChain.fromLLM({
  llm: new ChatOpenAI({ temperature: 0 }),
  graph: graph as any,
});

const response = await chain.run("Who played in Pulp Fiction?");
