feat: resolve Eloquent models in AsObject::run()

[faisuc]

When you call Action::run() with a scalar value (like an ID), it now automatically resolves it to an Eloquent model instance based on the method parameter type hints.

Example

class DeleteUser
{
    use AsAction;

    public function handle(User $user)
    {
        // $user is automatically a User model instance
    }
}
