test(run_all): параллельный запуск с логами по тестам и сводкой pass/fail

run_all.sh гонял набор последовательно с fail-fast: первый упавший тест
отменял всё остальное, а CI (xargs -P4) расходился с локальным порядком.
Теперь поддерживается -P N параллельность как в CI, ведётся лог по каждому
тесту, печатается сводка pass/fail и вывод упавших, принимаются фильтры имён
для запуска подмножества, а ошибки синтакс-проверки по-прежнему прерывают
всё до старта тестов.
