+ * Simplified Backwards Compatible MCP Client
+ * 
+ * This client demonstrates backward compatibility with both:
+ * 1. Modern servers using Streamable HTTP transport (protocol version 2025-03-26)
+ * 2. Older servers using HTTP+SSE transport (protocol version 2024-11-05)
+ * 
+ * Following the MCP specification for backwards compatibility:
+ * - Attempts to POST an initialize request to the server URL first (modern transport)
+ * - If that fails with 4xx status, falls back to GET request for SSE stream (older transport)
