//! Runtime HTTP/SSE API types and OpenAPI export (D16 E1-c, D17 frozen).
//!
//! Route handlers remain in `zagens-cli` **by design** (D17
//! Architecture Freeze). The engine→tools→route-handler closure forms an
//! internally co-located unit; further extraction would force artificial
//! trait hierarchies with a single implementation each. This crate is the
//! stable boundary for OpenAPI schema export, auth/cors middleware, wire
//! response types, and router composition helpers.
