Add a new capstone chapter (13_Multi_Agent_LangGraph) to both the DiskANN/NoSQL and vCore/DocumentDB guide variants, covering LangGraph core concepts, specialized agents, coordinator handoff, graph composition, and Azure Cosmos DB checkpointing/memory. Links out to the banking and travel multi-agent LangGraph workshops as next steps. Renumber Conclusion to chapter 14 and update both table-of-contents.
The LangGraph checkpointer (CosmosDBSaver) and the azure-cosmos-agent-memory toolkit used by the linked workshops target the Azure Cosmos DB for NoSQL API and do not apply to the vCore/DocumentDB (MongoDB) guide. Keep the multi-agent LangGraph chapter only in the NoSQL (diskann) derivative and restore the vCore table-of-contents and Conclusion numbering.

| - **[Banking multi-agent workshop (Python, LangGraph)](https://github.com/AzureCosmosDB/banking-multi-agent-workshop/tree/WorkShop_v2_PythonLangGraph)** - build a multi-tenant retail banking assistant with a coordinator agent that routes to specialized customer support, transactions, and sales agents. Demonstrates agent handoff, tool calling, vector search over an offers container, and Azure Cosmos DB checkpointing. | ||
| - **[Travel multi-agent workshop (Python, LangGraph)](https://github.com/AzureCosmosDB/travel-multi-agent-workshop/tree/agent_memory_toolkit_v2)** - build a travel-planning assistant with specialized hotel, dining, and activity agents coordinated by an orchestrator. Demonstrates the `azure-cosmos-agent-memory` toolkit for persistent agent memory, a Model Context Protocol (MCP) server, and deployment with the Azure Developer CLI (`azd up`). |

This is going to be rolled into main branch sometime next week. I'm finalizing a major update to do this now. This is fine for now. Will just need to remember to update after Aayush merges my changes.

This is great @TheovanKraay. My only feedback is that v2 branch on travel agent workshop is going to get merged into main branch in the next week or so.
