UI-Entwurf umgesetzt, Rocket.Chat-Tool, Deploymentcenter 2.4

Sicherungspunkt vor dem Aufraeumen. Buendelt die Arbeit, die seit dem
Abschluss der Avalonia-Portierung im Arbeitsverzeichnis lag.

Oberflaeche
- Entwurf aus Mockup/ umgesetzt: Theme.axaml (Farben je Thema, Barlow als
  mitgelieferte Schrift), Icons.axaml (Symbolgeometrien), Shell.axaml
  (eigene ControlThemes statt Fluent umzufaerben).
- Neue Steuerelemente StrokeIcon und BlueprintFrame, Seiten fuer
  Token-Verbrauch und Agenten-Chats, Werkzeug-Einstellungen als Seite
  statt eigenem Fenster, Texteditor-Fenster.
- ThemeManager mit hellem und dunklem Thema; die beiden Pinsel-Konverter
  entfallen, weil ein fester Farbwert den Themenwechsel nicht ueberlebt.

Rocket.Chat
- Neues Tool-Projekt (Client, Konfiguration, Workspace-Dateien) nach der
  Bauform des Telegram-Tools: rocketchat_poll als Tool-Job, geweckt wird
  nur, wenn wirklich etwas anliegt.
- send_file ist freigabepflichtig, send_message bewusst nicht: Der Raum
  ist Arbeitsraum, der Schutz sitzt an der Raum-Allowlist.
- Konzept-Doc um die Messung gegen die echte Instanz 8.7 ergaenzt; drei
  Annahmen waren falsch und sind korrigiert.

Deploymentcenter
- DC6 (Update anwenden) und DC7 (Erstinstallation ueber setup.json)
  erledigt, DC3 fuer win-x64/dev; deploy/publish.py als Release-Strecke.
- AppHost.DisposeAsync gegen doppeltes Herunterfahren gesperrt - sonst
  ueberschreibt eine zweite Abmeldung den Wartungszustand am Watchdog.
