/**
 * Keyless smoke for the SOURCE `dsh` launcher: run `apps/cli/src/bin.ts`
 * with the exact production launch vector (`node --import tsx/esm`, the same
 * shape as `bin/dsh` and the root `dsh`/`demo:tui`/`demo:web` scripts) and
 * assert the piped-stdio TTY refusal. The Node compatibility matrix runs this
 * WHOLE file, so a Node release changing module hooks or TypeScript handling
 * breaks this gate instead of every developer's `pnpm dsh`; the built-bin
 * suite covers the published `lib/` entry, not this source chain.
