Bug description

Inside of the rector config file, none of the classes from the Rector namespace are discovered---the ones from RectorLaravel are though

Steps to reproduce

• install rector
• create config file

// rector.php
<?php

declare(strict_types=1);

use Rector\CodingStyle\Rector\Enum_\EnumCaseToPascalCaseRector;
use Rector\CodingStyle\Rector\FuncCall\ArraySpreadInsteadOfArrayMergeRector;
use Rector\Config\RectorConfig;
use RectorLaravel\Rector\MethodCall\WhereToWhereLikeRector;
use RectorLaravel\Set\LaravelSetList;
use RectorLaravel\Set\LaravelSetProvider;

return RectorConfig::configure()
    ->withPaths([__DIR__ . '/app'])
    ->withParallel()
    ->withRules([
        ArraySpreadInsteadOfArrayMergeRector::class,
        EnumCaseToPascalCaseRector::class,
    ])
    ->withConfiguredRule(WhereToWhereLikeRector::class, [
        WhereToWhereLikeRector::USING_POSTGRES_DRIVER => true,
    ])
    ->withSetProviders(LaravelSetProvider::class)
    ->withPhpSets()
    ->withAttributesSets()
    ->withPreparedSets(
        codeQuality: true,
        codingStyle: true,
        deadCode: true,
        typeDeclarations: true,
        privatization: true,
        earlyReturn: true,
        phpunitCodeQuality: true,
    )
    ->withComposerBased(phpunit: true, laravel: true)
    ->withSets([
        LaravelSetList::LARAVEL_ARRAYACCESS_TO_METHOD_CALL,
        LaravelSetList::LARAVEL_CODE_QUALITY,
        LaravelSetList::LARAVEL_COLLECTION,
        LaravelSetList::LARAVEL_FACADE_ALIASES_TO_FULL_NAMES,
        LaravelSetList::LARAVEL_IF_HELPERS,
        LaravelSetList::LARAVEL_ELOQUENT_MAGIC_METHOD_TO_QUERY_BUILDER,
    ])
    ->withImportNames(removeUnusedImports: true);

I'm not on the project, but I investigated a bit.

Rector has file based autoloading and no PSR-4 mapping declared in the composer.json. They inject their own runtime autoloader function to look for Rector namespace prefixes.

The file loader includes rector/rector/bootstrap.php. That sets up their autoloader and requires __DIR__ . 'preload.php'

So, phpantom_lsp doesn't handle __DIR__ replacing, but even if it did, the preload.php does not require RectorConfig. It re-exports some nikic/php-parser classes.

I think this could be solved by bundling some Rector stubs along side the phpstorm stubs.
