feat(web-test): test CLI принимает несколько путей + флаг --url, fail-fast валидация

Привод контракта `run.mjs test` к общей практике (pytest/jest/playwright):
- позиционные аргументы = пути к тестам, можно несколько
  (`test a.test.mjs b.test.mjs dir/`); discoverTests объединяет, дедуплицирует,
  сортирует (порядок по числовым префиксам сохраняется);
- URL переехал из первого позиционного во флаг --url= (по умолчанию из
  webtest.config.mjs) — раньше url-первым путал: второй путь уходил в page.goto()
  и падал с криптовым 'Cannot navigate to invalid URL';
- fail-fast: несуществующий путь → понятная ошибка вместо падения goto;
  аргумент, похожий на URL, подсказывает про --url=.
