Add two widely-used accessibility analysis tools for HTML: - axe-core (15K+ GitHub stars, MPL-2.0): The industry standard for automated accessibility testing, used by Google Lighthouse and Microsoft Accessibility Insights. Tests against WCAG 2.0/2.1/2.2 guidelines. - Pa11y (4.5K+ GitHub stars, LGPL-3.0): Command-line accessibility testing tool with CI/CD integration support and multiple reporters. Both tools perform static analysis of HTML to identify accessibility violations (missing alt text, insufficient color contrast, missing ARIA attributes, heading hierarchy issues, etc.).

Summary
Adds two widely-used accessibility analysis tools to the HTML category:
axe-core (15K+ ⭐)
Pa11y (4.5K+ ⭐)
Why?
The list currently has no dedicated accessibility analysis tools despite accessibility testing being a major category of HTML static analysis. axe-core is arguably the most widely-used HTML analysis tool in the world (it powers Lighthouse's accessibility audit), and Pa11y is the go-to CLI tool for CI/CD integration.
