// build-webtest-db v0.1 — Собирает синтетическую web-test конфигурацию в постоянные пути
// и накатывает её в зарегистрированную базу `webtest` (см. .v8-project.json).
//
// Usage:
//   node tests/skills/build-webtest-db.mjs                 # пересобрать с нуля
//   node tests/skills/build-webtest-db.mjs --runtime python
//   node tests/skills/build-webtest-db.mjs --skip-platform # только XML, без db-create/load/update
//
// После завершения база готова к /web-publish + web-test сессии.
