/**
 * Filesystem MCP Server with LangGraph Example
 *
 * This example demonstrates how to use the Filesystem MCP server with LangGraph
 * to create a structured workflow for complex file operations.
 *
 * The graph-based approach allows:
 * 1. Clear separation of responsibilities (reasoning vs execution)
 * 2. Conditional routing based on file operation types
 * 3. Structured handling of complex multi-file operations
