/**
 * Pre-flight gate for `byline setup`. Policy:
 *
 * - Missing core `@byline/*` deps     → hard bail (seeds will throw on import).
 * - Missing both `.env` and `.env.local` → hard bail (every downstream phase
 *                                       reads them).
 * - Missing keys across either file   → warn and confirm (default No). Some
 *                                       keys may legitimately be supplied via
 *                                       shell env; the user is best placed
 *                                       to judge.
 *
 * `--yes` does NOT auto-confirm the soft warning — the default is No, so
 * `-y` against a partial env aborts. That matches the intent: `-y` is
 * "I don't want to type defaults," not "I don't care if my env is broken."
