Problem: Child nodes created via NodePicker while editing a parent node
would disappear when clicking "Done" on the modal. This caused:
- Child nodes not appearing in tree after closing modal
- Validation errors about non-existent nodes
- Tree unable to save
Root cause: Modal used structuredClone() to create local draft state,
which included a stale `children: []` array. When saving, this overwrote
the actual children that were added to the store via addNode().
Fix: Exclude `children` from the draft when saving, since children are
managed separately by addNode/deleteNode store actions.
Also documented this critical pattern in LESSONS-LEARNED.md for future
reference when implementing modals with local draft state.

Change 1: Add Cancel button and defer saving until Done is clicked
- NodeEditorModal now uses local draft state instead of updating store directly
- Cancel button discards changes; Done button commits to store
- If editing a brand new node, Cancel deletes it entirely
- NodeList tracks isEditingNewNode to pass to modal
Change 2: Inline node naming when creating from NodePicker dropdown
- Selecting "+ New Decision/Action/Solution" shows inline title input
- User enters title before node is created (Enter to create, Escape to cancel)
- Node appears in dropdown with human-readable title immediately
Change 3: Improved dropdown labels
- Format changed from "UUID (UUID...)" to "Title (UUID...)"
- Untitled nodes show "Untitled Question" or "Untitled {type}"
- Root node shows "Root Question (root)" when empty
