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

## Summary

A routine patch-level npm dependency update was prepared for the target repository `github/gh-aw-firewall` (referenced here as plain text, not a link, since this issue lives in the control-plane repo `githubnext/gh-aw-cao`).

- **Package**: `js-yaml`
- **Change**: `5.3.0` → `5.4.1` (patch)
- **Files**: `package.json` (direct dependency + the `overrides` pin, which references `$js-yaml` so both stay in lockstep), `package-lock.json`
- **Reason**: routine freshness — `js-yaml` is exact-pinned and one patch release behind. No open security advisory triggered this.
- **Reachability**: direct runtime dependency, imported at runtime by `src/topology.ts`, `src/config-writer.ts`, `src/compose-network-conflicts.ts`, `src/rules.ts`, `src/compose-sanitizer.ts`, `src/config-file.ts` (YAML parsing for compose/firewall config files — not on an auth/crypto/payment path).
- **Risk**: low, patch-level, high confidence. `npm audit` shows 0 vulnerabilities before/after.

Because this run's `safe_output_mode` is `review`, no pull request was opened directly. Instead a review bundle artifact was published containing the diff (`changes.patch`), validation notes, and a merge-ready PR description.

Validation performed

- Manual smoke test of the newly resolved `js-yaml@5.4.1` module: `yaml.load(...)` / `yaml.dump(...)` round-tripped correctly.
- `npm audit --registry=https://registry.npmjs.org/`: 0 vulnerabilities before and after.
- `npm install --package-lock-only --registry=https://registry.npmjs.org/` cleanly regenerated the lockfile entries for both the direct dependency and the `overrides` pin.
- **Limitation**: the full Jest suite could not be run in this sandbox — installing the complete devDependency tree (jest, ts-jest, babel, typescript, etc.) via the public npm registry exceeded the available time budget. The repository's configured registry (an internal Azure Artifacts feed) also returned `403 Forbidden` for `js-yaml` in this sandbox, so discovery/validation used the public `registry.npmjs.org` instead — the proposed change itself does not touch `.npmrc`/registry config, so CI in the real environment should resolve normally.
- Recommend running the existing CI test suite (`npm test`) on the real PR to confirm the js-yaml consumers listed above still pass before merge.

### Next step for a maintainer with target-repo write access
Open a pull request in `github/gh-aw-firewall` bumping `js-yaml` from `5.3.0` to `5.4.1` in `package.json` (both the direct dependency and the `overrides` entry) and regenerating `package-lock.json`, using the review bundle artifact from this run as the starting patch.

In github/gh-aw-firewall, inspect package.json and package-lock.json for the js-yaml dependency and overrides pin. Start by applying the review bundle's dependency diff, then run npm test in the target repository. Done means both entries resolve to 5.4.1, the lockfile is regenerated, and the existing test suite passes.
