feat: expand execute tool into child tool spoilers when script has tool calls

- Если execute скрипт содержит tools.<server>.<tool>(...) — показываем
  отдельные спойлеры для каждого найденного инструмента
- Если нет вызовов инструментов — показываем execute как обычно
- Args для дочерних инструментов извлекаются из кода regex
