//! Durable workflow engine core for A3S.
//!
//! `a3s-flow` models the Workflow SDK style of durable execution as a Rust
//! core: workflow runs are event-sourced, step results are persisted, waits and
//! hooks suspend without burning compute, and the actual workflow interpreter is
//! a pluggable runtime. The native TypeScript runtime boundary compiles source
//! once, then invokes the compiled executable through a small JSON protocol.
