// Spawn `tsx watch` with stdin ignored.
//
// tsx watch listens on stdin for its press-Return-to-restart shortcut. Under turbo on Windows that
// inherited handle never delivers and never closes, and the watched service then never reaches its
// entrypoint: no output, no port, no error. These services are non-interactive, so nothing is lost.
// The redirect lives here rather than in the dev scripts because `< NUL` and `< /dev/null` differ.
