Major refactoring cleanup: - Add new controller architecture (class-controller-*.php) - Add new settings-v2 UI (views/settings-v2/) - Add new CSS architecture (agentic-sidebar.css, tokens) - Add esbuild build pipeline (scripts/build.js, package.json) - Add composer dependencies (vendor/) - Add frontend src directory (assets/js/src/index.jsx) - Add documentation files - Remove old/obsolete files (class-settings.php, old CSS) This commits all pending changes from previous refactoring efforts.
