* chore: refresh vendored js-yaml to 4.3.2 (#4565)

lint-vendored-deps caught the drift: this PR's lockfile-only bump left
gsd-core/bin/lib/vendor/js-yaml.cjs and the package.json pin behind the
new js-yaml 4.3.2 resolved by package-lock.json (merge-key CPU-limit
backport, GHSA for excessive merge-key processing). Refreshes the
vendored copy from node_modules and bumps the manifest pin to match.

+**Patched a CPU-exhaustion issue in the vendored YAML parser (`js-yaml` 4.3.2)** — merge-key processing in YAML documents now counts empty mapping merges toward the existing `maxTotalMergeKeys` limit, closing a gap upstream backported from 5.4.1 (nodeca/js-yaml#797).
