fix(python): Entfernt inkompatibles response_mime_type Argument

Behebt den TypeError beim Aufruf von GenerationConfig in der älteren Version der google-generativeai Bibliothek, indem das nicht unterstützte Argument entfernt wird.

+## 5. Aktuelle Probleme und Debugging-Protokoll (Stand: 2025-12-21)
+
+Wir stecken derzeit in einem hartnäckigen `ImportError: cannot import name 'cygrpc' from 'grpc._cython'` Fehler fest, der beim Starten des Python-Skripts (`market_intel_orchestrator.py`) auftritt.
+
+**Bisher unternommene Schritte zur Problemlösung:**
+
+1.  **Virtuelle Umgebung (.venv) erstellt:** Um Paketkonflikte zu isolieren.
+2.  **`python3.11-venv` installiert:** Um `venv` unter Debian/Ubuntu zu ermöglichen.
+3.  **`requirements.txt` bereinigt und Paketversionen gepinnt:**
+    *   `requests==2.28.2` und `urllib3==1.26.18` (behob `TypeError: 'type' object is not subscriptable`).
+    *   `typing-extensions==4.5.0` (behob `AttributeError: module 'typing' has no attribute '_SpecialGenericAlias'`).
+    *   `google-generativeai==0.4.0` (gepinnt, um Kompatibilität mit älteren `google-api-core` und `grpcio` zu erzwingen).
+    *   `grpcio==1.54.2` und `google-api-core==2.11.1` (gepinnt, sollte `cygrpc` beheben, hat es aber nicht).
+4.  **`gemini_api_key.txt` geprüft:** Sichergestellt, dass nur der reine API-Schlüssel enthalten ist.
+5.  **Gemini-Modell gewechselt:** Von `gemini-1.5-flash` zu `gemini-pro`, dann `responseMimeType` zu `text/plain` geändert (dies war eine Umgehung zur Diagnose, der `404 Not Found`-Fehler trat weiterhin auf, was auf ein tieferes Autorisierungs- oder Kompilierungsproblem hindeutet).
+6.  **Node.js API-Brücke (`server.cjs`) angepasst:** Sichergestellt, dass der Python-Subprozess mit dem korrekten Venv-Interpreter und der `PYTHONPATH` gestartet wird (behob `ModuleNotFoundError: No module named 'requests'`).
+7.  **`grpcio` deinstalliert und Build-Tools installiert:** `build-essential` und `python3-dev` wurden installiert, um eine Kompilierung von `grpcio` aus dem Quellcode zu ermöglichen.
+
+**Aktuelles Problem:**
+
+Der Fehler `ImportError: cannot import name 'cygrpc' from 'grpc._cython'` bleibt bestehen, selbst nach dem Versuch, `grpcio` neu zu kompilieren (der Kompilierungsschritt selbst konnte nicht vollständig durchgeführt werden).
+
+Dieser Fehler ist ein Indikator dafür, dass die **vor-kompilierten `grpcio`-Wheels** nicht mit der spezifischen Systemumgebung (Python-Version, Betriebssystem, installierte Bibliotheken) kompatibel sind, oder dass die **Kompilierung aus dem Quellcode fehlschlägt**, weil immer noch eine Abhängigkeit oder ein Build-Tool auf Systemebene fehlt oder inkompatibel ist.
+
+**Mögliche nächste Schritte (manuell durch den Benutzer):**
+
+-   **Erneuter Versuch der `grpcio`-Kompilierung:** Führen Sie den Befehl `pip install --no-binary :all: grpcio==1.54.2` erneut aus. Beobachten Sie die Ausgabe genau auf Kompilierungsfehler. Der Prozess kann sehr lange dauern.
+-   **Upgrade/Downgrade der Python-Version:** Das Problem könnte mit Python 3.11 spezifisch sein. Ein Versuch mit Python 3.10 oder 3.9 könnte helfen, ist aber ein größerer Eingriff ins System.
+-   **Docker-Ansatz vorziehen:** Die sauberste und reproduzierbarste Lösung wäre, den gesamten Backend-Stack in einem Docker-Container zu betreiben. Innerhalb eines Dockerfiles können wir die Umgebung exakt steuern und die Installation der Abhängigkeiten von Grund auf neu aufbauen, was solche `cygrpc`-Probleme oft umgeht.
