When you use any of the Queue inspect methods ie reservedJobs etc sometimes... you just want a bit more.. CONTEXT

A lot of Jobs you'll just have a generic wrapper, such as a PodcastJob, it would be very helpful to be able to just get a bit of context when things like deployments are happening which are useful for observability ie so we know more context about that exact job thats holding deployments etc.

This adds a HasContext interface, that you implement and return an array of what you need in the context() method take below as an example....:

class AgentJob implements ShouldQueue, HasContext
{
    public function context(): array
    {
        return [
            'provider' => $this->provider,
            'model'    => $this->model,
        ];
    }
}

This means you can just do...

 Queue::reservedJobs()->first()->context

And instantly, we have more details so I can easily see "Hmm.. this agent is always slow around deployments" etc etc..

The context is saved to the job payload, so it shouldn't be a book, just nice details you need... no idea

Used an interface cause I can't think of a nicer non b/c way unless you're happy to just method_exists it...

I went with context, as it felt right, but open to renaming it.
