Phase 3: Avalonia-Bedienhuelle fuer Windows und Linux
Neues Projekt Predictalytics.Shell (Avalonia 12.1.1, net10.0) als plattformuebergreifender Ersatz fuer den WinForms-Host. Setzt auf dem in Phase 2 extrahierten Predictalytics.Hosting auf. Oberflaeche: - MainWindow mit Menue, Werkzeugleiste, Terminal-Tab, Einstellungen-Tab und Statusleiste. Die feste Fenstergroesse von 1886x1088 ist aufgeloest. - Terminal als ListBox ueber ObservableCollection mit Einfaerbung nach Loglevel. Ringpuffer statt des bisherigen kompletten Leerens bei 500 Zeilen. - Einstellungsansicht handgeschrieben als Ersatz fuer den PropertyGrid, den es in Avalonia nicht gibt: vier Gruppen, Passwortfelder, mehrzeiliges Textfeld fuer die Egress-Kanaele, ComboBox fuer den SSL-Modus. Gespeichert wird explizit statt bei jeder Einzeloperation. - LicenseWindow ersetzt den WinForms-LicenseDialog. - Dialogs.cs als schlanker Ersatz fuer MessageBox.Show, ohne Drittanbieter. Headless-Modus (--headless) im selben Binary: fuer Linux-Server ohne Desktop-Session. Die Argumentauswertung steht vor jeder Avalonia- Initialisierung, sonst stirbt der Prozess ohne X11 bevor der Schalter greift. Lizenz ueber PREDICTALYTICS_LICENSE_KEY statt Dialog, SIGTERM und SIGINT ueber PosixSignalRegistration fuer sauberes systemd-Stop. Exit-Codes: 0 planmaessig, 2 keine nutzbare Lizenz, 3 Fehler. Plattformdetails: Schrift-Fallbackkette fuers Terminal, Avalonia.Fonts.Inter als mitgelieferte UI-Schrift, UTF-8 fuer die Windows-Konsole im Headless-Modus. Die Avalonia-Basisklasse wird als global::Avalonia.Application angegeben: innerhalb von Predictalytics.* loest der kurze Name auf den eigenen Namespace Predictalytics.Application auf. Build: 0 Fehler, 0 Warnungen. Tests: 100 bestanden. Verifiziert: --headless laeuft bis zur Lizenzschranke und beendet sich mit Exit-Code 2; GUI startet und zeigt das Lizenzfenster. Das Hauptfenster konnte nicht geprueft werden, weil die hinterlegte Lizenz abgelaufen ist. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
