Adds a navigation-aware request cancellation mechanism that automatically aborts all route-specific API requests when the user navigates to a different route. This prevents silent state-update errors from responses arriving after component unmount and conserves bandwidth by cancelling now-irrelevant requests. Key additions: - NavigationCancellationContext: Context for managing route-specific signals - NavigationCancellationProvider: Provider that detects route changes and aborts all signals from the previous route - useNavigationAbortSignal hook: Allows components to subscribe to navigation-aware cancellation signals - Comprehensive tests for the cancellation lifecycle - Documentation in Web-Development.md for request lifecycle policy The provider is placed in the app hierarchy between BrowserRouter and AuthProvider, ensuring consistent cancellation behavior across all routes. Long-lived background tasks (polling, session validation) can opt-out by managing their own AbortController lifecycle. Closes #23 from Tasks.md: No global cancellation policy on route transitions Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
