feat(ui): Bilder aus der Zwischenablage ins interaktive Terminal einfuegen

Ctrl+V mit einem Bild in der Zwischenablage schreibt es als temporaeres PNG unter ~/.claudeDo/tmp/ und fuegt den Pfad in den Composer ein, genau wie ein Datei-Drop -- Claude liest die Datei selbst. Text-Paste laeuft unveraendert ueber den bestehenden bracketed-paste-Pfad. Avalonia 12.0.4 liest Clipboard-Bitmaps bereits selbst (IClipboard. TryGetDataAsync + AsyncDataTransferExtensions.TryGetBitmapAsync), kein Win32-P/Invoke noetig. Alte Tmp-Dateien (>24h) werden beim App-Start aufgeraeumt (ClaudeDo.App/Program.cs), keine eigene Aufraeum-Infrastruktur.
