feat(node-editor, blueprint): add group box and math/logic nodes (#438)

* feat(node-editor, blueprint): add group box and math/logic nodes

node-editor:
- Add visual group box for organizing nodes
- Dynamic bounds calculation based on node pin counts
- Groups auto-resize to wrap contained nodes
- Dragging group header moves all nodes together

blueprint:
- Add comprehensive math nodes (modulo, power, sqrt, trig, etc.)
- Add logic nodes (comparison, boolean, select)

docs:
- Update nodes.md with new math and logic nodes
- Add group feature documentation to editor-guide.md

* chore: remove unused debug and test scripts

Remove FBX animation debug scripts that are no longer needed:
- analyze-fbx, debug-*, test-*, verify-*, check-*, compare-*, trace-*, simple-fbx-test

Remove unused kill-dev-server.js from editor-app

+## Node Grouping
+
+You can organize multiple nodes into a visual group box to help manage complex blueprints.
+
+### Creating a Group
+
+1. Box-select or Ctrl+click to select multiple nodes (at least 2)
+2. Right-click on the selected nodes
+3. Choose **Create Group**
+4. A group box will automatically wrap all selected nodes
+
+### Group Operations
+
+| Action | Method |
+|--------|--------|
+| Move group | Drag the group header, all nodes move together |
+| Ungroup | Right-click on group box → **Ungroup** |
+
+### Features
+
+- **Dynamic sizing**: Group box automatically resizes to wrap all nodes
+- **Independent movement**: You can move nodes within the group individually, and the box adjusts
+- **Editor only**: Groups are purely visual organization, no runtime impact
