## Summary

Added dedicated component for sampling previews and change all image
outputs (outputs, videos, previews) to be responsive and respond to node
resizing.

## Changes

- **What**: Implemented `LivePreview` component for mid-execution
sampling visualization with responsive layout system
- **Dependencies**: Added resize handle composable and transform state
integration

## Review Focus

Node resize interaction conflicts with canvas dragging, and image
dimension calculation performance during rapid sampling updates.
