Тесты выводных уроков глушили console.log студента строкой
vi.spyOn(console, 'log').mockImplementation(() => {}): вызовы писались в
spy.mock.calls (поэтому assert работал и задание засчитывалось), но
настоящей печати не было — на панели «вывод» студент своего результата
не видел.

Сняли .mockImplementation(() => {}) в 44 test.js — шпион теперь и
записывает вызовы (assert цел), и вызывает настоящий console.log.
Добавили disableConsoleIntercept: true в vitest.config.js, чтобы вывод
шёл в stdout чисто, без служебного префикса vitest (stdout | test.js > ...).
Это прямой аналог pytest --capture=no из фикса Python.

Невыводные уроки (проверяют возвращаемое значение) и 10-basics/20-comments
не менялись.

Имя теста в каждом из 71 test.js теперь равно слагу урока (каталог без
числового префикса, дефисы → пробелы): 'hello world', 'string concatenation',
'if', 'while', 'define function' и т.д. Раньше было 'hello world' у выводных
и разрозненные 'test'/'mirror'/'printNumbers'. Теперь на панели «вывод»
заголовок кейса отражает тему урока. Только строка-описание, на assert не влияет.
