Pull Request Title

feat(components): add unified ODE components package with platform-specific implementations

Description

This PR introduces a new @ode/components package that provides a comprehensive, unified component library for the ODE ecosystem. The package includes platform-specific implementations optimized for both React Web and React Native, all built on the @ode/tokens design system for consistent styling across applications.

Components Added:

• Button: Custom design with fading border effect, hover states, and support for paired buttons with opposite styling
• ButtonGroup: Container component for managing paired button styling and interactions
• Input: Modern, minimalist input with validation states and accessibility features
• Card: Clean card component with subtle elevation and hover effects
• Badge: Simple badge component for labels and status indicators

Key Features:

• Platform-specific implementations in src/react-web/ and src/react-native/
• Shared types and utilities in src/shared/
• Token-based styling using @ode/tokens
• Dark mode support
• WCAG compliant accessibility
• TypeScript support with full type definitions
• Modern, minimalist design aesthetic

Package Structure:

• 21 files total including configuration, documentation, and source files
• Comprehensive README.md and CONTRIBUTING.md documentation
• Ready for integration into formulus, formulus-formplayer, and other ODE applications
