Bilal Muhammad Khan d847a50369 feat(auth): implement complete authentication foundation (Phases 1-7)
Complete implementation of authentication system for Todo Evolution Hackathon Phase II:

Backend (FastAPI):
- User registration and login endpoints with JWT authentication
- Argon2id password hashing and HS256 JWT signing
- Rate limiting (5/min login, 100/min global) to prevent brute force
- Security headers (HSTS, CSP, X-Frame-Options, etc.)
- Structured JSON logging with request ID tracking
- Database migrations with Alembic
- Connection pooling and async operations
- 57 unit and integration tests (pytest)

Frontend (Next.js 16):
- Registration and login pages with form validation
- Dashboard with protected routes
- Reusable UI components (Input, Button, ErrorMessage)
- Middleware for authentication and authorization
- Accessibility features (ARIA labels, keyboard navigation)
- 13 E2E tests with Playwright

Testing & Quality:
- 70 total automated tests (100% passing)
- 80%+ test coverage (constitutional requirement met)
- Security validation (password hashing, JWT, rate limiting)
- Accessibility testing (ARIA, keyboard navigation)

Tech Stack:
- Backend: Python FastAPI, SQLModel, Neon PostgreSQL, Alembic
- Frontend: Next.js 16 (App Router), TypeScript, Tailwind CSS
- Auth: Better Auth patterns with JWT
- Testing: pytest, pytest-cov, Playwright

Constitutional Compliance:
✅ 80%+ test coverage
✅ Type safety throughout
✅ Security best practices
✅ Documentation inline
✅ Spec-driven development
