feat: Add Cursor setup step to UI setup wizard

- Introduced a new `CursorSetupStep` component for optional Cursor CLI configuration during the setup process.
- Updated `SetupView` to include the cursor step in the setup flow, allowing users to skip or proceed with Cursor CLI setup.
- Enhanced state management to track Cursor CLI installation and authentication status.
- Updated Electron API to support fetching Cursor CLI status.
- Marked completion of the UI setup wizard phase in the integration plan.
