- Remove wrapping ScrollViewer from live output TextBox — Avalonia
TextBox with AcceptsReturn handles its own scrolling; nested
ScrollViewer caused layout collapse
- Auto-scroll via CaretIndex instead of removed ScrollViewer
- Add OnWindowClosed to both editor ViewModels, ensuring the
TaskCompletionSource always resolves when the dialog closes
(including via X button), preventing RelayCommand from staying
permanently disabled
