Review prompt fidelity and bound correction to one rechecked attempt

 - Textsuche und Bedeutungssuche mit Embeddings. „Auto“ kombiniert beide; ähnliche Ergebnisse sind Vorschläge, keine garantierten Treffer.
 - OpenAI-kompatible API-Basis-URL, optionaler API-Key, Modellscan über `/models`, getrennte Chat- und Embedding-Modelle. Optional separater Embedding-Endpoint.
 - KI-Vorschläge für Kategorie, Tags und Kurzbeschreibung; vor dem Speichern manuell übernehmen.
+- Zweiter Modellaufruf prüft die Bedeutungstreue. Bei Abweichungen folgen höchstens eine Korrektur und eine erneute Prüfung (2–4 Aufrufe). Befunde und Fehler erscheinen am Entwurf; Modellprüfung ist keine Garantie. Manuelle Änderungen am Vorschlag setzen den Prüfstatus zurück.
 - KI-Überarbeitung als bearbeitbarer Vorschlag neben dem Original. Erst Übernehmen und Speichern ändert den Prompt.
 - Privater MCP-Server über Streamable HTTP, nur lesend: `search_prompts`, `get_prompt`, `list_categories`, `get_prompt_versions`.
 - JSON-Export und Import inklusive Versionen, ohne Modell-API-Keys.
