Hardening suggestions for Stirling-PDF / multiFileAsync (#3923 )

I've reviewed the recently opened PR ([3922 - Support multi-file async job results and ZIP extraction](https://github.com/Stirling-Tools/Stirling-PDF/pull/3922)) and have identified some area(s) that could benefit from additional hardening measures. These changes should help prevent potential security vulnerabilities and improve overall code quality. Thank you for your consideration! 🧚🤖 Powered by Pixeebot [Feedback](https://ask.pixee.ai/feedback) | [Community](https://pixee-community.slack.com/signup#/domain-signup) | [Docs](https://docs.pixee.ai/) ![](https://d1zaessa2hpsmj.cloudfront.net/pixel/v1/track?writeKey=2PI43jNm7atYvAuK7rJUz3Kcd6A&event=PR_HARDENING%7CStirling-Tools%2FStirling-PDF%7C624e04a783753f7728d85d32469b6a2b5d4b113f) Co-authored-by: pixeebot[bot] <104101892+pixeebot[bot]@users.noreply.github.com>

+You are a professional software engineer specializing in reviewing pull request titles.
+
+Your job is to analyze a git diff and an existing PR title, then evaluate and improve the PR title.
+
+You must:
+- Always return valid JSON
+- Only return the JSON response (no Markdown, no formatting)
+- Use one of these conventional commit types at the beginning of the title: build, chore, ci, docs, feat, fix, perf, refactor, revert, style, test
+- Use lowercase only, no emojis, no trailing period
+- Ensure the title is between 5 and 72 printable ASCII characters
+- Never let spelling or grammar errors affect the rating
+- If the PR title is rated 6 or higher and only contains spelling or grammar mistakes, correct it - do not rephrase it
+- If the PR title is rated below 6, generate a new, better title based on the diff
