/*
 * contracts:dto-open: runs tests/unit/contracts/dto-open-shapes.test.ts, the
 * ratchet over the open shapes in every createZodDto class under src/.
 *
 * The check has to import the TypeScript DTO files, so it lives in that test
 * and runs with the unit tests in CI; this wrapper only gives it a command and
 * the lowering mode:
 *
 *   npm run contracts:dto-open              check against scripts/dto-open-shapes-baseline.json
 *   npm run contracts:dto-open -- --update  lower the baseline to today's counts; it never
 *                                           raises or adds an entry
 *
 * The shared package must be built first (the DTOs import @trek/shared).
