Adds the ability to set the AssignWorker attribute not only directly on Workflow or Activity classes, but also on their parent classes.

This PR introduces a feature that automatically registers activities and workflows with a designated worker when they implement a specific interface. This functionality applies to both Activity and Workflow classes.

Here's an example in PHP to illustrate the concept:

use Spiral\TemporalBridge\Attribute\AssignWorker;
use Temporal\Activity\ActivityInterface;
use Temporal\Workflow\WorkflowInterface;

#[AssignWorker(name: 'some-worker')]
#[ActivityInterface]
interface SomeActivityInterface
{
    // Interface methods for activities
}

#[AssignWorker(name: 'some-worker')]
#[WorkflowInterface]
interface SomeWorkflowInterface
{
    // Interface methods for workflows
}

With this implementation, any activity or workflow that implements SomeActivityInterface or SomeWorkflowInterface, respectively, will be automatically registered with the some-worker.

This enhancement streamlines the process of linking workers to both activities and workflows, ensuring a more efficient and consistent setup with minimal manual configuration.
