Important

This PR improves stability and error handling by adding an ErrorBoundary component, enhancing task management, and introducing a LongRunningOperationIndicator for better UI feedback.

    • Introduced ErrorBoundary component in ErrorBoundary.tsx to catch and display errors in the UI.
    • Wrapped App component with ErrorBoundary in App.tsx.
  • Task Management:
    • Enhanced error handling and state reset in Task.ts for streaming operations and task abortion.
    • Improved task cancellation and history management in ClineProvider.ts with timeout and error logging.
  • UI Enhancements:
    • Added LongRunningOperationIndicator in LongRunningOperationIndicator.tsx to show progress and allow cancellation of long-running tasks.
    • Integrated LongRunningOperationIndicator in ChatRow.tsx for streaming API requests.
  • Miscellaneous:
    • Added ErrorBoundary usage in AppWithProviders in App.tsx.
    • Improved timeout handling in ClineProvider.ts for task abort operations.
