Bilal Muhammad Khan 18a3ee83c1 feat(frontend): implement complete design system with shadcn/ui components
Implement comprehensive frontend design system for Phase II web application:

- Add shadcn/ui component library (button, input, card, dialog, form, etc.)
- Refactor auth pages (login/register) with new design system
- Update dashboard with modern UI components
- Implement TypeScript schemas for tasks, tags, filters, and users
- Add authentication and dashboard-specific components
- Create comprehensive documentation (accessibility, performance, validation)
- Configure Tailwind with custom theme and animations
- Add context providers for state management

This establishes the complete UI foundation required for the hackathon Phase II deliverable.
