/// Minimal test helper for `src/hooks/external.rs` unit tests.
///
/// Usage:
///   hook_echo '<json>'          — print json to stdout, exit 0
///   hook_echo '<json>' <code>   — print json to stdout, exit <code>
///   hook_echo --exit <code>     — exit with <code> (no output)
///
/// Compiles to `target/debug/hook_echo` (or release). Unit tests locate it
/// at runtime via the CARGO_MANIFEST_DIR compile-time env var.
