/// Build the workflow HTTP API router. The `gate` argument is the
/// wire-boundary auth layer; the embedder supplies it as a closure
/// that wraps the authed portion of the router (typically
/// `|r| r.layer(my_auth_middleware)`). The type signature makes the
/// gate **non-optional** — you cannot construct an unauthenticated
/// workflow router.
///
/// The closure receives only the authed portion. `health`, `version`,
/// `openapi.json`, and `docs` are merged outside the gate so probes
/// can reach them without a bearer token.
