//! MCP (Model Context Protocol) client + [`McpToolset`].
//!
//! Supports two transports:
//!
//! - **stdio** — spawn an MCP server as a child process, talk newline-delimited
//! JSON-RPC over stdin/stdout. The classic local-server form.
//! - **streamable HTTP** — POST JSON-RPC to a single HTTP endpoint. Responses
//! come back as either `application/json` (single result) or
//! `text/event-stream` (SSE). Mirrors the MCP 2025-03 spec onward.
