Explain Laravel Queues and how to implement background job processing.

Laravel Queues allow deferring time-consuming tasks:\n\n**Job Creation:**\n```bash\nphp artisan make:job ProcessPayment\n```\n\n**Job Implementation:**\n```php\nclass ProcessPayment implements ShouldQueue {\n use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;\n \n protected $order;\n \n public function __construct(Order $order) {\n $this->order = $order;\n }\n \n public function handle() {\n // Process payment logic\n PaymentGateway::charge($this->order);\n }\n \n public function failed(Exception $exception) {\n // Handle job failure\n }\n}\n```\n\n**Dispatching Jobs:**\n```php\n// Dispatch immediately\nProcessPayment::dispatch($order);\n\n// Dispatch with delay\nProcessPayment::dispatch($order)->delay(now()->addMinutes(10));\n\n// Dispatch to specific queue\nProcessPayment::dispatch($order)->onQueue('payments');\n```
