feat: поддержка Go и npm экосистем

- setup-nexus.sh: создание go-proxy (proxy.golang.org) и npm-proxy (registry.npmjs.org)
- nexus_client.py: extract_go_info() и extract_npm_info() для парсинга путей
  Go:  packages/github.com/gorilla/mux/@v/v1.8.0.zip → name=github.com/gorilla/mux ver=v1.8.0
  npm: packages/lodash/-/lodash-4.17.21.tgz → name=lodash ver=4.17.21
- nexus_client.py: EXTRACTORS dict + extract_package_info() универсальный extractor
- webhooks.py: _detect_ecosystem() — определяет экосистему из asset.format
- harvester.py: использует extract_package_info() вместо extract_pypi_info()
- Всё в Docker-контейнере, на хосте ничего не ставится
- GuardDog поддерживает go и npm из коробки
