refactor(proxy-client): упростить установщик пакета и shell-тесты

- install.sh ставит три прямые ссылки без Stow; чужие файлы не трогает
  и перечисляет все конфликты сразу; ~/.local и ~/.config могут быть
  ссылками; блок в ~/.bashrc дописывается, если нет маркера.
- proxy_on читает вывод proxy-client env без временного файла.
- Тесты Bash-функций работают через поддельный PROXY_CLIENT_BIN.
- test_proxy_client_full.sh запускает только тесты proxy-client,
  прогон под Python 3.8 — если есть uv.
