Clone local task on commerce product pages causes a fatal error when local tasks are built for a non-product route

Problem/Motivation

Since 1.2.2, the module registers a "Clone" local task (commerce_quick_node_clone.node.quick_clone) on entity.commerce_product.canonical, with access controlled by a custom access callback:

commerce_quick_node_clone.node.quick_clone:
  path: '/clone/{node}/edit'
  defaults:
    _controller: '\Drupal\commerce_quick_node_clone\Controller\QuickNodeCloneNodeController::cloneNode'
    _title: 'Clone product'
  requirements:
    _custom_access: '\Drupal\commerce_quick_node_clone\Controller\QuickNodeCloneNodeAccess::cloneNode'
  options:
    _admin_route: TRUE
    parameters:
      node:
        type: entity:commerce_product

QuickNodeCloneNodeAccess::cloneNode(AccountInterface $account, $node) has no default value for $node. When Drupal's local task plugin manager (\Drupal\Core\Menu\LocalTaskManager) evaluates access for this local task plugin outside of an actual product route context — e.g. any code that calls getLocalTasks() / getTasksBuild() for the current route while browsing a route that has no node route parameter at all — ArgumentsResolver cannot resolve the $node argument and throws:

RuntimeException: Callable "Drupal\commerce_quick_node_clone\Controller\QuickNodeCloneNodeAccess::cloneNode" requires a value for the "$node" argument. in Drupal\Component\Utility\ArgumentsResolver->handleUnresolvedArgument() (line 149 of core/lib/Drupal/Component/Utility/ArgumentsResolver.php).

This is the same failure mode already fixed upstream in the sibling module Quick Node Clone, see #3431222: RuntimeException: Callable QuickNodeCloneNodeAccess::cloneNode requires a value for the "$node" argument, where the accepted resolution was to give $node a default value of NULL. That fix was never carried over to this module.

Steps to reproduce

1. Enable Commerce Quick Node Clone 1.2.2+ together with Commerce Product.
2. As an authenticated user with permission to see the admin toolbar, trigger a build of the current route's local tasks through the local task plugin manager (\Drupal::service('plugin.manager.menu.local_task')->getLocalTasks($route_name, 0)) while browsing any route other than entity.commerce_product.canonical — for example from custom code that lists "current page" local tasks in a toolbar/admin menu.
3. The page returns a 500 with the RuntimeException above instead of simply omitting the "Clone" tab.

Proposed resolution

Give $node a default value of NULL in QuickNodeCloneNodeAccess::cloneNode(). The method body already handles a non-ProductInterface, non-scalar value correctly by falling through to AccessResult::forbidden(), so no other logic changes are required. Patch attached; a merge request with the same change is also linked once opened.
