Add Pompelmi: Node.js file-upload malware scanner

[SonoTommy]

This PR adds Pompelmi to the Web → Development section.

Pompelmi is an MIT-licensed, open-source file-upload malware scanner for Node.js / TypeScript applications. It’s designed to make file uploads safer by providing:

• strict MIME sniffing and extension validation,
• protection against ZIP-bombs and deeply nested archives,
• optional YARA-based scanning,
• ready-made adapters for Express, Fastify, Koa and Next.js, plus a CLI for CI pipelines.

I’ve placed it under Web → Development because it’s a developer-focused security tool intended to be integrated directly into web backends and CI workflows.
