Fix inherited PHPDoc / annotation type resolution

[ragulka]

Summary

When a child class inherits a property with a @var docblock annotation from a parent class in a different namespace, the type transpiler incorrectly resolves class references using the child class's namespace context. This causes types like SimpleGenericClass<int, string> to resolve as TypeScriptUnknown when the child doesn't import the referenced class.

Example

// Parent — namespace App\Models
class Parent {
    /** @var string[]|SimpleGenericClass<int, string> */
    public array $items;
}

// Child — namespace App\Models\Children (different namespace, no import)
class Child extends Parent {
    public string $ownProperty;
}

Transforming Child would produce unknown for the $items type instead of correctly resolving SimpleGenericClass.

Fix

In ClassTransformer::getTypeScriptNode(), when the annotation comes from the property's own @var docblock (rather than a class-level @property or constructor @param on the current class), use the declaring class's namespace context for type resolution.

This distinction matters because:

• Class-level @property and constructor @param annotations are written in the current class's context and should resolve against its namespace
• Property @var annotations belong to the declaring class and should resolve against that class's namespace
