Update Decision Engine and related components for WP-25a: Bump version to 1.2.0, enhance multi-stream retrieval with pre-synthesis compression, and integrate Mixture of Experts (MoE) profile support. Refactor chat interface to utilize new compression logic and llm_profiles for improved synthesis. Maintain compatibility with existing methods and ensure robust error handling across services.

 DESCRIPTION: Hybrid-Client für Ollama, Google GenAI (Gemini) und OpenRouter.
-             Verwaltet provider-spezifische Prompts und Background-Last.
-             WP-20: Optimiertes Fallback-Management zum Schutz von Cloud-Quoten.
-             WP-22/JSON: Optionales JSON-Schema + strict (für OpenRouter).
-             WP-25: Integration der DecisionEngine für Agentic Multi-Stream RAG.
-VERSION: 3.4.2 (WP-25: Ingest-Stability Patch)
+             WP-25a: Implementierung der Mixture of Experts (MoE) Profil-Steuerung.
+VERSION: 3.5.0 (WP-25a: MoE & Profile Orchestration)
 STATUS: Active
 FIX: 
-- Ingest-Stability: Entfernung des <5-Zeichen Guards (ermöglicht YES/NO Validierungen).
-- OpenRouter-Fix: Sicherung gegen leere 'choices' zur Vermeidung von JSON-Errors.
-- Erhalt der vollständigen v3.3.9 Logik für Rate-Limits, Retries und Background-Tasks.
+- WP-25a: Profilbasiertes Routing via llm_profiles.yaml.
+- WP-25a: Unterstützung individueller Temperaturen pro Experten-Profil.
+- WP-25: Beibehaltung der Ingest-Stability (kein Schwellenwert für YES/NO).
+- WP-25: Erhalt der vollständigen v3.4.2 Resilienz-Logik.
