Fileoverview
Race a promise against an AbortSignal with deterministic
listener cleanup on the body-wins path.
Remarks
Centralizes the abort-race pattern that previously lived inline in
createWorkerHost's call proxy and restart(). WHATWG DOM guarantees
signal.reason is defined on an aborted signal; the ?? fallback exists
solely for runtimes whose polyfills diverge from spec.
