`ping` unsupported before `initialize`

You need to create the server as stateful without session ID.

rmcp::transport::streamable_http_server::StreamableHttpServerConfig {
            sse_keep_alive: Some(std::time::Duration::from_secs(15)),
            stateful_mode: false, // Stateless mode: no session persistence
        },

It's unclear to me if this behavior is or is not spec compliant
