Add context-aware child-creation shortcuts to nodes#show

parent_match Procs on CccConventions::NODE_KINDS, matched against
unique_path, decide which "add child" kinds show on a given node. Fixes
nodes#new not honoring a pre-selected kind (radio group and parent-field
visibility both defaulted to "generic" unconditionally).
