build(deps-dev): bump prettier from 3.8.4 to 3.9.4 in /actions/setup/js

[dependabot]

Summary

Bumps prettier from 3.8.4 to 3.9.4 in actions/setup/js.

Changes

File	Change
actions/setup/js/package.json	prettier devDependency version range updated from ^3.8.4 to ^3.9.4

Impact

• Scope: Development tooling only (devDependencies). No production runtime code is affected.
• Risk: Low. This is a minor version bump within the ^3.x semver range. Prettier 3.9.x maintains backward compatibility with 3.8.x.
• Components affected: Code formatting in actions/setup/js JavaScript/TypeScript build toolchain.

Prettier 3.9.x release highlights

Prettier 3.9 introduces incremental formatting improvements and bug fixes. See the Prettier changelog for details.

Ran the PR finisher pass on 7300a01. There are no in-scope review threads, the branch is clean locally, and make fmt, make lint, make test-unit, make test, and make recompile all passed. Existing CI on this head is stale/action-required rather than a code failure, so a maintainer still needs to re-trigger PR checks before merge.

• ✅ Reviews — no new in-scope review feedback beyond this PR-finisher request was available to act on in this pass.
• ✅ Checks (local) — make fmt, make lint, make test-unit, make test, and make recompile all passed on 7300a01.
• ❓ Checks (CI) — unverified on the current agent head and still needs a human re-trigger; I could not inspect prior GitHub check details from this environment because the GitHub API requests returned 403.
• ❓ Mergeable — the branch is up to date with origin/main locally and the PR diff is only the Prettier bump files, but I could not confirm GitHub’s PR mergeable state from this environment because gh pr view returned 403.

Actions taken: revalidated the branch locally and confirmed the PR diff remains limited to actions/setup/js/package.json and actions/setup/js/package-lock.json.
Hand-off: CI must be re-triggered by a maintainer (close/reopen PR, workflow_dispatch, or push) before merge.
Still needed: a maintainer should re-trigger PR checks and confirm GitHub reports the PR as mergeable.
