* fix(website): remediate WCAG accessibility issues and add axe regression guardrail Fixes accessibility violations found by an axe-core sweep of every website page in both light and dark themes: - aria-allowed-role (WCAG 1.3.1, 4.1.2): the shared resource card rendered an <article> with role="listitem", which is not an allowed role for that element. Switched the wrapper to a <div role="listitem"> so the listitem role is valid (affected every card, e.g. #arcade-canvas on /extensions/). - aria-required-children (WCAG 1.3.1): removed role="list" from the tools, contributors, and cookbook containers whose children are not list items. - nested-interactive (WCAG 4.1.2): removed tabIndex=0 from extension cards and rendered the author as a non-interactive span so no interactive control is nested inside another (the author link remains in the modal). - color-contrast (WCAG 1.4.3): gave .btn-primary explicit white text with an AA-compliant hover (#7326d6), and bumped the dark-theme secondary text gray (--sl-color-gray-3) to #84849c (5.32:1) so ToC / meta / footer text passes. Adds a checked-in regression guardrail: - website/scripts/a11y-audit.mjs runs axe-core over all routes in both themes against the production build and fails on critical/serious violations only (moderate/minor are reported but non-blocking). Transitions/animations are disabled before sampling so axe measures settled, steady-state colors instead of mid-theme-transition frames. - Adds npm scripts (website:a11y at the root, a11y in website/) and README docs. The matching Build Website CI step is proposed in the PR description (omitted from this commit because the authoring token lacks workflow scope).

Removing the shell layer keeps signal delivery / detached-PGID shutdown predictable; resolving Astro's bin and running it with process.execPath also avoids the EINVAL that modern Node raises when spawning the npx.cmd shim without a shell on Windows.

Install a Plugin
For most users, the Awesome Copilot marketplace is already registered in the Copilot CLI/VS Code, so you can install a plugin directly:
copilot plugin install <plugin-name>@awesome-copilot
If you are using an older Copilot CLI version or a custom setup and see an error that the marketplace is unknown, register it once and then install:
copilot plugin marketplace add github/awesome-copilot
copilot plugin install <plugin-name>@awesome-copilot
