Update: File Upload Cheat Sheet — add a small Node.js example #2105

Description

What is missing or needs to be updated?

The current File Upload Cheat Sheet already covers important protections such as content-type validation, file signature validation, risky archive handling, antivirus/sandbox usage, and automation in file review.

However, it does not currently include a small Node.js-oriented implementation example in the "File Content Validation" section. Adding one concise example could help Node.js developers translate the existing guidance into practice.

How should this be resolved?

Add one short, neutral sentence in the "File Content Validation" section, near the paragraph that discusses automation and scanning, for example:

In Node.js environments, libraries such as Pompelmi can help implement pre-storage inspection of untrusted uploads, including file signature checks, MIME mismatch detection, and risky archive inspection.

This would be a single-file documentation update only, with no structural rewrite and no new section. The goal is not to promote a product, but to provide a small implementation-oriented example for Node.js developers.
