Fix: Match short namespace symbols

[eliashaeussler]

Problem

When using short namespaces instead of full namespaces, the symbol should properly match in order to detect usages of a required package.

Example

A package with PSR-4 namespace Cocur\Slugify\ is required. The project code base contains the following class:

<?php

use Cocur\Slugify;

final class MyBeautifulClass
{
    public function __construct(
        private readonly Slugify\Slugify $slugify,
    ) {
    }
}

In this example, the namespace symbol would not match, because the registered PSR-4 namespace contains a trailing backslash whereas the imported namespace in the class does not.

Solution

To resolve incorrect behavior in such cases, a trailing backslash is now always appended to the constructed namespace symbols.
