Module design 

Centralized design system for VT Code.

This crate provides a single source of truth for all design system concerns:

• Color conversion: Unified anstyle to ratatui color mapping
• Style bridging: Conversion between styling frameworks
• Design constants: Shared UI constants (ellipses, spacing, breakpoints)
• Layout: Responsive layout mode logic
• Panel: Base panel widget primitive
• Diff formatting: Unified diff rendering with ANSI colors
• List rows: Canonical modal/command row builders (list)
• Keyboard copy: Shared interaction hints (keys)
