* Initial plan

* Apply security updates to dependencies

- Update yarn.lock with fixed versions of vulnerable packages
- Add package-lock.json to .gitignore (yarn is primary package manager)
- Fix 3 vulnerabilities: @babel/helpers, brace-expansion, and js-yaml
- Reduce total vulnerabilities from 13 to 10
