Complex Workflow Orchestration

Implement a scenario where the agent needs to handle a complex guest request, such as 'I'd like to extend my stay by two nights, and also arrange for a late checkout and an airport shuttle.' The agent should sequentially use multiple tools (e.g., check room availability, modify booking, schedule transport) and leverage memory from Milvus. Demonstrate the agent's thought process and tool calls as traced by Langfuse.
