Document or add CI (pytest + JS lint)

Source: gitlab-issues-export.md (Issue 2)

Weight: 3

Problem / context

codereview.md states CI should run pytest and lint on every PR; this clone has no .gitlab-ci.yml or .github/workflows. Quality relies on local discipline.

Suggested approach / acceptance criteria

• Add a minimal GitLab CI .gitlab-ci.yml or document a recommended pipeline in CONTRIBUTING.md (job names, cache, Python image, pytest, npm ci && npm run lint:js).
• Fail pipeline on pytest or ESLint errors.

Status update (Jun 2026): No .github/workflows\ or .gitlab-ci.yml\ in repo. Quality gates are local-only (pytest, ESLint via npm). Dockerfile was added (\a8bec9) but no automated CI pipeline yet.
