//! Pure-function reducer: `fn update(State, Msg) -> (State, Vec<Cmd>)`.
//!
//! Heart of the MVU architecture. Everything here is synchronous,
//! does no I/O, and is testable without tokio or a terminal. The
//! effect runner (`crate::effect`) takes the `Cmd` values the reducer
//! emits and performs the actual work; results come back as `Msg`
//! events that feed into another `update` call.
//!
//! The split is load-bearing: stale events racing with cancellation,
//! lost tool results, and two event loops competing for input are all
//! impossible to express against these types.
