// Regression fixture: Rust async flow through `tokio::process::Command`.
//
// Per docs/language-maturity.md, Rust's Tokio process variants are not
// yet covered, the Tokio async process APIs are a known gap.  The
// fixture is checked in so that when Rust async-process coverage lands,
// the engine begins producing the intended finding and the
// `forbidden_findings` assertion forces whoever adds the coverage to
// update this expectation.
