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.

+     * Create a project map (similar to a sitemap) of project.
+     *
+     * The Reflection component is capable of analyzing one or more files into a hierarchy of objects representing the
+     * structure of your project. It does this by analyzing the source code of each individual file using the
+     * `analyze()` method in the Analyzer class.
+     *
+     * Because the Analyzer class requires a whole series of objects that interact together a factory method `create()`
+     * is available. This method instantiates all objects and provides a reasonable default to start using the Analyzer.
+     *
+     * There is also a Service Provider (`\phpDocumentor\Descriptor\ServiceProvider`) that can be used with either Silex
+     * or Cilex instead of using the factory method; this will make it easier to plug in your own features if you want to.
