Problem
The lint CI workflow runs on every PR but its status is not visible in README.md. A status badge would give contributors and users immediate confidence that the repo's structure is validated.
Expected behavior
Add a GitHub Actions status badge for the lint workflow to the README badge row:
```markdown

```
