chore(deps): bump js-yaml to 4.2.0 — clear GHSA-h67p-54hq-rp68 (#1338)

js-yaml <= 4.1.1 has a quadratic-complexity DoS in merge-key handling via
repeated aliases (GHSA-h67p-54hq-rp68 / CVE-2026-53550, medium). Patched in
4.2.0. js-yaml is dev-only here (direct devDependency + deduped transitive via
eslint/@eslint/eslintrc), so shipped users are not exposed; the bump clears
Dependabot alert #9 and patches the floor. The existing ^4.1.1 range already
permitted 4.2.0 — this only refreshes the stale lockfile pin. npm audit: 0
vulnerabilities.
