Fix issue #866 where the metadata hook's async wrapper used *args/**kwargs
which caused AttributeError when ComfyUI's make_locked_method_func tried
to access __func__ on the func parameter.
The async_map_node_over_list_with_metadata wrapper now uses the exact
same signature as ComfyUI's _async_map_node_over_list:
- Removed: *args, **kwargs
- Added: explicit v3_data=None parameter
This ensures the func parameter (always a string like obj.FUNCTION) is
passed correctly to make_locked_method_func without any type conversion.
