- Add BroadcastChannel API for real-time logout synchronization across tabs
- Implement storage event listener as fallback for older browsers
- When a user logs out in one tab, all other tabs immediately reflect the logout state
- Update tests to verify storage event and BroadcastChannel behavior
- Update Architecture.md to document cross-tab synchronization
- Update Web-Development.md with authentication state management notes
The provider now broadcasts logout messages to other tabs so they immediately
reflect the logout state without requiring a page refresh or additional API calls.
The implementation uses BroadcastChannel as the primary sync mechanism with
storage events as a fallback for older browsers.
