/**
 * Keyless smoke for SOURCE `dsh` execution: run `apps/cli/src/bin.ts`
 * with the exact production runtime vector (`node --import tsx/esm`, the
 * vector the root `dsh` script invokes directly) and assert the
 * required-config diagnostic. 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.
