[dependabot:release-train-updater] Dependency update ready for review: js-yaml 5.3.0 → 5.4.1 in github/gh-aw-firewall

A dependency review bundle has been published as a workflow artifact for the target repository `github/gh-aw-firewall` (rendered as plain text, not a link, per review-mode routing rules).

### Summary
- Package: `js-yaml` (npm), direct runtime dependency
- Manifest: root `package.json` / `package-lock.json`
- Version: `5.3.0` → `5.4.1` (patch)
- Security advisories: none found (checked `ajv`, `chalk`, `commander`, `execa`, `js-yaml` via GitHub Advisory DB — 0 vulnerable)
- Reachability: actively imported in `src/compose-sanitizer.ts`, `src/rules.ts`, `src/config-file.ts`, `src/topology.ts`, `src/compose-network-conflicts.ts`, `src/config-writer.ts` (YAML parsing for compose/config files — security-sensitive surface, but patch-level change with no known breaking changes)
- `Smart-Dependabot-Merge-Candidate: yes` (non-major, no security concern, clean lockfile resolution)

Other outdated deps (`chalk` 4→6, `commander` 12→15, `execa` 5→10) are all major bumps and were intentionally excluded from this bundle to keep the change small and reviewable; they should be evaluated separately if desired.

### Validation performed
- `npm outdated` against public registry (repo's configured private registry mirror doesn't yet host `js-yaml@5.4.1`)
- GitHub Advisory Database check — 0 vulnerabilities
- `npm install js-yaml@5.4.1 --save-exact --package-lock-only` — updated manifest + lockfile cleanly

**Not run in this sandbox:** full `npm install`/`npm test` (slow/registry-mirror limitations). A maintainer or CI should run `npm install && npm test` against the repo's real registry before merging.

### Next step
A maintainer with write access to `github/gh-aw-firewall` should download the published review-bundle artifact from this workflow run, apply the included patch (`changes.patch`) to a new branch, and open the pull request directly in `github/gh-aw-firewall` (this control-plane repository does not have write access to that target).

Agent prompt

Apply the attached `changes.patch` from the review bundle artifact to a new branch off `main` in `github/gh-aw-firewall`, run `npm install && npm test`, and open a PR titled "Bump js-yaml from 5.3.0 to 5.4.1" using the summary in `summary.md` as the PR body. Verify CI passes before requesting review.

**Action:** Maintainer of `github/gh-aw-firewall` should retrieve the review bundle artifact from this run and open the PR directly in the target repo; acceptance check is CI (install + test) passing on the new branch.

Retrieve the published review-bundle artifact from the workflow run and apply changes.patch in github/gh-aw-firewall. Check the root package.json and package-lock.json, then run npm install && npm test against the repository's real registry. Done means the dependency update is applied and CI passes.
