Add comprehensive toast notification component to feedback category

- Create new toast component with full TypeScript implementation
- Add SCSS styling using semantic design tokens exclusively
- Implement size variants (sm, md, lg) and color variants (primary, success, warning, danger, info)
- Include interactive features: auto-dismiss, manual dismiss, progress bar, hover pause/resume
- Add comprehensive accessibility support with ARIA attributes and keyboard navigation
- Create engaging demo component with interactive examples and live statistics
- Integrate toast into feedback category menu and routing system
- Follow established component patterns and design system conventions
