Nodes with children can now be edited

Editing used to be limited to leaves. The reasoning was sound and the rule was too blunt. The thing worth protecting is an answer written against wording you are about to change, not the shape of the tree.

A node is now editable as long as nothing in its subtree holds an AI answer. A branch of plain notes, or of prompts nobody has run yet, is yours to rewrite. A node with an answer anywhere beneath it stays locked, because changing it would leave that answer arguing with a question that no longer exists.

This is what makes a cloned template usable. Clone a skeleton, edit its structural nodes to fit your situation, then run the prompts.

The server enforces the same rule as the canvas. It used to reject any edit to a node with children, which meant an edit the interface allowed could be silently dropped.

Open a map and edit a node that has children.
