feat(parser): реализован парсинг новых файлов

- Добавлена поддержка формата *.xyz, что расширило возможности анализа проектов.
- Реализована функция `parse_xyz` в файле [`archdoc-core/src/parser.rs`](archdoc-core/src/parser.rs:42) для чтения и валидации содержимого.
- Обновлены тесты в [`archdoc-core/tests/parser_tests.rs`](archdoc-core/tests/parser_tests.rs:15) для покрытия нового формата.
- Обновлена документация в `README.md` с примерами использования нового парсера.
