Hi! I'd like to suggest aura-lint for the QA Tools section.

While it's a newer project and still gathering its first hundreds of stars (hence the unchecked box), it solves a very modern and specific problem that traditional tools like ESLint don't handle well out of the box.

It is a zero-dependency, ultra-fast UI architecture and Tailwind CSS linter. Its key features include:

1. An autonomous Auto-Fix Engine (--fix) that corrects hardcoded anti-patterns (e.g., converting text-[13px] or #ff0000 to standard or custom semantic CSS variables).
2. Dynamic Theme Reading that automatically learns a project's CSS variables.
3. A built-in plugin scaffolding system for teams to write their own specific UI rules.

It's fully tested, documented, and actively maintained. I believe it would be a very useful and unique addition to your QA Tools list. Thank you!
