Backports the Set-based !!omap key-uniqueness fix (GHSA-5p4m-2wfm-xmqj / CVE-2026-59870): resolveYamlOmap() used O(n^2) Array.indexOf, allowing quadratic CPU on untrusted YAML. Impact scope: a11y-critical (dependency tree only — no rule or module behaviour changes). Dev-only exposure: no runtime `dependencies` declared, js-yaml comes via the build/test toolchain. Overrides-only change; lockfile regenerated with npm install --package-lock-only. npm audit reports no js-yaml findings after the bump. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
