Rueckmeldung nach Vertrauensstufe: drei Wege nach oben (#715)

- IAgentTool.ReadsForeignContent: Werkzeuge mit Aussenkontakt erklaeren sich selbst
  (WebFetch, WebMonitor, DirectAPI, Mail, RocketChat, Telegram, TelegramClient,
  SocialMediaManager, FTP, Database); AgentConfig.TreatAsForeignReader kann nur verschaerfen
- ReportingLine: Stufe aus den Werkzeugen, "wer steht darueber", Pruefung des Wegs nach oben
  (nie Aenderungen an Aufgaben darueber, nur eine Ebene hoch, Fremdinhalt-Stufe gar kein
  Freitext) und Rahmung als untrusted_content
- Engine: Nachricht und Spawn nach oben geprueft, Text der Fremdinhalt-Stufe kommt gerahmt an
- Taskboard: task_create/update/comment, reopen und die Dubletten-Notiz folgen dem Berichtsweg
- Dispatcher: Aufgaben von Agenten der Fremdinhalt-Stufe gehen gerahmt in den Lauf
- TaskReports: Erledigt-Signal und Systemmeldung (in Pruefung, blockiert, abgebrochen) an den
  Auftraggeber, je Zustand einmal, gesammelt in einer offenen Aufgabe je Empfaenger
- OrgBriefing nennt den Berichtsweg; WebUI zeigt Stufe und Schalter am Agenten
