## Summary
Consolidates Tailwind configuration and styles into a shared
`@comfyorg/design-system` package for reuse across monorepo apps.
The goal was not to make changes to how the design system works; merely
to separate it cleanly. I _would_ strongly recommend some drastic
sweeping changes, however I believe that should be done after the
migration.
## Changes
- **What**: Migrates CSS files, Tailwind config, and custom icons to
design-system package
- **Dependencies**: Moves `@iconify-json/lucide` and `@iconify/tailwind`
to design-system package
