Drop internal plan references from code comments

The pack cited internal planning-doc items (plan P3-7, decision D1, plan
risk 9.2) that aren't public, leaving outside contributors with pointers
they can't follow. Each comment already states its reason; only the
dangling citation is removed.

 is estimated from its widget count, and nodes stack per column with a fixed
 vertical gap — so no template can ship with overlapping nodes at default sizes.
