Add Code tab with JSX export and syntax highlighting

- sceneNodeToJsx() in @open-pencil/core: converts SceneNode subtree to JSX
- CodePanel.vue with Prism.js highlighting, line numbers, copy button
- Third tab in properties panel: Design | Code | AI
- 14 new tests covering shapes, text, layout, effects, multi-selection

#### Implementation order
1. JSX renderer in `@open-pencil/core` (port from figma-use)
2. Chat panel UI — `ChatPanel.vue`, `useChat()`, message list, tool timeline, `⌘J` toggle
3. API key settings — input UI, Stronghold storage (Tauri) / localStorage (browser)
4. Core tools — render, set_fill, set_layout, set_text, snapshot, get_selection
5. Screenshot + diff tools
6. Comment pin system
7. Full tool set (remaining 118 tools)
1. ✅ JSX renderer in `@open-pencil/core` (port from figma-use)
2. ✅ Chat panel UI — `ChatPanel.vue`, `useChat()`, message list, tool timeline, `⌘J` toggle
3. Code panel — "Code" tab in properties panel, JSX export with syntax highlighting
- `sceneNodeToJsx()` in `packages/core/src/render/export-jsx.ts` (reverse of renderer.ts)
- `CodePanel.vue` with Prism.js highlighting, copy button, reka-ui ScrollArea
- Third tab in PropertiesPanel: Design | Code | AI
- Subtree export: full JSX tree for selection, multi-selection separated by blank lines
4. API key settings — input UI, Stronghold storage (Tauri) / localStorage (browser)
5. Core tools — render, set_fill, set_layout, set_text, snapshot, get_selection
6. Screenshot + diff tools
7. Comment pin system
8. Full tool set (remaining 118 tools)
#### Validation
