//! Typed compare-and-swap executor for synchronous and asynchronous workflows.
//!
//! `CasExecutor<T, E>` binds the shared state type `T` and operation error type
//! `E`. Each execution call introduces its own business output type `R`, so one
//! executor configuration can serve multiple CAS operations over the same state.
