refactor: Cleanup git state - commit all staged changes

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.

+# Doctrine Instantiator
+
+This library provides a way of avoiding usage of constructors when instantiating PHP classes.
+
+[![Build Status](https://travis-ci.org/doctrine/instantiator.svg?branch=master)](https://travis-ci.org/doctrine/instantiator)
+[![Code Coverage](https://codecov.io/gh/doctrine/instantiator/branch/master/graph/badge.svg)](https://codecov.io/gh/doctrine/instantiator/branch/master)
+[![Dependency Status](https://www.versioneye.com/package/php--doctrine--instantiator/badge.svg)](https://www.versioneye.com/package/php--doctrine--instantiator)
+
+[![Latest Stable Version](https://poser.pugx.org/doctrine/instantiator/v/stable.png)](https://packagist.org/packages/doctrine/instantiator)
+[![Latest Unstable Version](https://poser.pugx.org/doctrine/instantiator/v/unstable.png)](https://packagist.org/packages/doctrine/instantiator)
+
+## Installation
+
+The suggested installation method is via [composer](https://getcomposer.org/):
+
+```sh
+composer require doctrine/instantiator
+```
+
+## Usage
+
+The instantiator is able to create new instances of any class without using the constructor or any API of the class
+itself:
+
+```php
+$instantiator = new \Doctrine\Instantiator\Instantiator();
+
+$instance = $instantiator->instantiate(\My\ClassName\Here::class);
+```
+
+## Contributing
+
+Please read the [CONTRIBUTING.md](CONTRIBUTING.md) contents if you wish to help out!
+
+## Credits
+
+This library was migrated from [ocramius/instantiator](https://github.com/Ocramius/Instantiator), which
+has been donated to the doctrine organization, and which is now deprecated in favour of this package.
