toolbox/Docker/dockerfile linter

Dockerfile linter

hadolint-style static checks: pinning, layer hygiene, root user, secrets.

about this tool

Paste an existing Dockerfile and get line-numbered findings with fixes: unpinned base images, ADD where COPY suffices, curl|sh installs, secrets in ENV, apt cache bloat and more.

It is heuristic linting, not a substitute for hadolint in CI — but it catches the classics before review.
