//! MCP story tools — create, update, move, and manage stories, bugs, refactors,
//! spikes, and epics via MCP.
//!
//! This module is a thin adapter: it deserialises MCP payloads, delegates to
//! `crate::service::story` and `crate::http::workflow` for business logic,
//! and serialises responses.
