Implements user interface for viewing and managing active sessions:
Session Management Features:
- SessionsManagement component with full session management UI
- List all active sessions with device information
- Platform-specific icons (Computer, Phone, Tablet)
- Current session indicator with green chip
- Session details: device fingerprint, platform, last used, created date
- Revoke individual sessions with confirmation dialog
- Revoke all sessions except current with bulk action
- Real-time session count display
User Experience:
- Visual device type indicators
- Human-readable time formatting (e.g., "2 hours ago")
- Current session clearly marked and protected from removal
- Warning dialogs before revoking sessions
- Success/error feedback with alerts
- Loading states for all operations
- Empty state handling
API Integration:
- Sessions API client in lib/api/sessions.ts
- Get all sessions
- Get session count
- Revoke specific session
- Revoke all sessions except current
- Proper error handling and user feedback
Settings Page Integration:
- Added Sessions Management section

Implemented comprehensive rate limiting for API security:
- Created custom Next.js-native rate limiter using in-memory store
- Added 5 rate limit configurations:
- authLimiter: 5 requests/15min for login/register/password-reset
- aiLimiter: 10 requests/hour for AI assistant queries
- trackingLimiter: 30 requests/min for activity tracking
- readLimiter: 100 requests/min for read-only endpoints
- sensitiveLimiter: 3 requests/hour for sensitive operations
- Applied rate limiting to endpoints:
- /api/auth/login, /api/auth/register, /api/auth/password-reset
- /api/ai/chat
- /api/tracking/feeding (GET and POST)
- Rate limit responses include standard headers:
- RateLimit-Limit, RateLimit-Remaining, RateLimit-Reset
- Retry-After header with seconds until reset
- Tested with 7 sequential requests - first 5 passed, last 2 blocked with 429
Note: Current implementation uses in-memory store. For production with
multiple instances, migrate to Redis-backed storage for distributed
rate limiting.

Implemented React error boundaries to catch and handle errors gracefully:
**Core Error Handling Components:**
- Created ErrorBoundary class component with error catching and logging
- Created specialized fallback UIs (MinimalErrorFallback, DataErrorFallback,
ComponentErrorFallback, FormErrorFallback, ChartErrorFallback, ImageErrorFallback)
- Added withErrorBoundary HOC for easy component wrapping
- Created errorLogger service with Sentry integration placeholder
**Error Logging Service (errorLogger.ts):**
- Centralized error logging with severity levels (FATAL, ERROR, WARNING, INFO, DEBUG)
- Context enrichment (URL, userAgent, timestamp, environment)
- Local storage of last 10 errors in sessionStorage for debugging
- User context management (setUser, clearUser)
- Breadcrumb support for debugging trails
**App Integration:**
- Wrapped root layout with top-level ErrorBoundary for catastrophic errors
- Added NetworkStatusIndicator to main page for offline sync visibility
- Wrapped daily summary section with isolated DataErrorFallback
- Added error boundary to AI assistant page with ComponentErrorFallback
- Wrapped feeding tracking form with FormErrorFallback using withErrorBoundary HOC
- Protected analytics charts with isolated ChartErrorFallback boundaries
**Error Recovery Features:**
- Isolated error boundaries prevent cascade failures
- Retry buttons on all fallback UIs
- Error count tracking with user warnings
- Development-mode error details display
- Automatic error logging to service (when Sentry integrated)
Next: Integration with Sentry for production error tracking
