Pa11y Accessibility Testing CLI and CI

Pa11y is a real open-source accessibility testing tool that lets agents audit pages for WCAG issues from the command line or in CI. This skill uses Pa11y to turn page-level accessibility checks into actionable reports with issue counts, selectors, and remediation context.
