Remove supra brand from design system

Supra (VivoKey MD3 theme) has been extracted into a standalone
Dangerous-Pi theme plugin. Remove all supra references from tokens,
web CSS, showcase apps, and documentation.

- Delete supra brand tokens and elevation.css
- Update ThemeBrand type to "dt" | "classic"
- Remove supra from CSS generation, imports, and bevels
- Update CLAUDE.md and package READMEs
