vintner: bump to 0.3.0, auto-install shell completion

Wires vintner's own `completion bash|zsh` output into Stapler's
install-completion helper (bash -> /usr/share/bash-completion/
completions/vintner, zsh -> /usr/share/zsh/site-functions/_vintner -
both verified against a real built package, since neither path nor
the required paired files-find() registration is documented anywhere
reachable). Completion now works immediately after `stplr install`,
no manual `source <(vintner completion bash)` needed.

0.3.0 also picks up upstream's signal-forwarding fix (a wine
subprocess no longer survives `vintner` being killed by PID) and its
own expanded test coverage.

 - Версия поднята до `0.2.0`: добавлена поддержка сборки KMDF/UMDF-драйверов
   через Windows Driver Kit (`download --with-wdk`), короткие алиасы команд
   и локализация CLI на английский и русский (`VINTNER_LANG`).
+- Версия поднята до `0.3.0`: пакет теперь сам регистрирует автодополнение
