//! End-to-end smoke test for the `html-to-markdown mcp` stdio server.
//!
//! Drives the real binary over the MCP stdio transport (newline-delimited
//! JSON-RPC): initialize, then list tools, prompts, and resources. Asserts the
//! tools carry read-only annotations and the typed config schema, and that the
//! prompt and resource catalogs are advertised. The protocol mechanics are
//! rmcp's responsibility — this is one happy-path wiring check across every
//! capability the server exposes.
