Full optimization: 38 improvements across frontend, backend, infrastructure, and docs

Frontend (17 items):
- Virtualized message list with batch loading
- CSS split with skeleton, drawer, search filter, message action styles
- Code splitting via React.lazy + Suspense for Admin/Ethics/Settings pages
- Skeleton loading components (Skeleton, SkeletonCard, SkeletonGrid)
- Debounced search/filter component (SearchFilter)
- Error boundary with fallback UI
- Keyboard shortcuts (Ctrl+K search, Ctrl+Enter send, Escape dismiss)
- Page transition animations (fade-in)
- PWA support (manifest.json + service worker)
- WebSocket auto-reconnect with exponential backoff (10 retries)
- Chat history persistence to localStorage (500 msg limit)
- Message edit/delete on hover
- Copy-to-clipboard on code blocks
- Mobile drawer (bottom-sheet for consensus panel)
- File upload support
- User preferences sync to backend

Testing (8 items):
- Component tests: Toast, Markdown, ChatMessage, Avatar, ErrorBoundary, Skeleton

- E2E smoke tests (5 tests)
- Accessibility audit utility

Backend (12 items):
- Vector memory with cosine similarity search
- TTS/STT adapter factory wiring
- Geometry kernel with orphan detection
- Tenant registry with CRUD operations
- Response cache with TTL
- Connection pool (async)
- Background task queue
- Health check endpoints (/health, /ready)
- Request tracing middleware (X-Request-ID)
- API key rotation mechanism
- Environment-based config (settings.py)
- API route documentation improvements

Infrastructure (4 items):
