Fix `aprx_error!`

[zenna]

aprx_error! is broken because after adding ports to a CompArrow, it's parent needs to be updated.

There are more fundamental changes to all the core data-structures which may make this problem go away, but for now we need a quick fix.

Approaches

• Make aprx_totalize use walk! instead of lightwalk.
• After adding a node, somehow traverse to parent and update it at that tiem Have a genericclean` function which fixes these issues in the parent/

I think the first of these is probably the easiest.
