- ✅ Add `activityStatus` state and `handleCancel` to App.tsx; update Escape handler
- ✅ Extend `onClaudeMessage` handler: tool_progress, task_progress, restructure result block
- ✅ Pass `activityStatus` and `onCancel` props to `<ChatPane>` in App.tsx
- ✅ Update ChatPane.tsx props interface and loading bubble render
- ✅ Add loading bubble CSS (flex layout, cancel × styles, pulse animation)
