ESLint plugin enforces auth protection on Next.js routes

Minor Changes

• Add an experimental ESLint plugin @clerk/eslint-plugin, with a single require-auth-protection rule for the Next.js App router. This rule helps enforce auth protections are present at the page/route/server function level. (#8704) by @Ephem

  The lint rule offers an editor quick-fix suggestion for unprotected resources that inserts await auth.protect() at the top of the function. Suggestions are opt-in and are not applied by eslint --fix.

  Includes a bulk auto-fixer, available as the clerk-next-fix-auth-protection command. It lints with your existing ESLint config and applies the await auth.protect() suggestion to every resource it can safely fix, reporting the rest as needing manual attention. Supports --dry-run.
