//! `ExecProbe` / `ExecStore` (issue #838 slice 1) bincode roundtrip tests.
//!
//! These are the caller-owned-tool variants: the Python (or other foreign)
//! orchestrator runs the tool itself, calls `ExecProbe` to ask the daemon
//! whether the (name + inputs + env + extra) tuple already has a cached
//! result, and posts the bytes via `ExecStore` on a miss.
