Enhance codebase with various improvements and fixes

- Updated compile options for modular build to conditionally disable optimizations in non-release configurations.
- Added <future> header to distributed_token_blacklist.h for future support.
- Changed mutex members in mysql_importer.h and postgres_importer.h to mutable for thread safety.
- Introduced audit_logger_ in query_engine.h for telemetry tracking.
- Removed redundant includes in shard_router.h.
- Cleaned up unused RocksDB includes in distributed_token_blacklist.cpp.
- Refactored federated_learning.cpp to use trimmed mean for aggregation.
- Fixed vector data handling in vector_index.cpp for HNSW indexing.
- Used static_cast for GPU memory management in active_vram_allocator.cpp.
- Updated LlamaWrapper to improve tokenization and error handling.
- Added shared_mutex for thread-safe configuration management in knowledge_gap_detector.cpp.
- Enhanced replication_manager.cpp with better WAL entry serialization.
- Improved gossip_config_manager.cpp to track propagation latency with proper type casting.
- Added version token generation in redundancy_strategy.cpp.
- Enhanced shard_router.cpp with detailed documentation for routing methods.
- Updated wal_storage.cpp to use [[maybe_unused]] for bounds-safe overloads.
- Added new configuration files for remote agents and MCP servers.
- Adjusted test cases for AQL hardening and distributed token blacklist to reflect recent changes.

   - Validierung: `Build_CMakeTools` fuer Target `themis_server` erfolgreich (result code 0; Rebuild inkl. `lockfree_metrics.cpp`).
 
+- [x] QW-core-06: RedisCache-Subscriber-Shutdown interruptible machen (thread_join_no_timeout Hardening).
+  - Umsetzung: In `redis_cache` ersetztes reconnect-slice-sleep durch `condition_variable::wait_for` mit Stop-Pruefung; `shutdown()` signalisiert jetzt aktiv per `notify_all()` vor `join()`.
+  - Validierung: Isolierter Core-Build erfolgreich mit `cmake --build --preset windows-release --target themis_base --parallel 16`; dazu Editor-/Compile-Diagnostics fuer `redis_cache.{h,cpp}` sauber.
+
+- [x] QW-core-07: Generated-Protobuf-Warnungsrauschen (C4267) auf Source-Ebene kapseln.
+  - Umsetzung: In `cmake/CMakeLists.txt` gezielte MSVC-Source-Property `COMPILE_OPTIONS "/wd4267"` nur fuer generierte Protobuf-Translation-Units (`themis_wire_v1.pb.cc`, `themisdb.pb.cc`, `themisdb.grpc.pb.cc`), inkl. bestehender Unity-Excludes im Modularpfad.
+  - Validierung: Re-Configure + Build (`CMake: Configure (windows-release)`, `CMake: Build (windows-release)`) ohne C4267-Treffer im Build-Log.
+
+- [x] QW-core-08: MSVC D9025 Flag-Konflikt (`/O2` vs `/Od`) im Modular-Serverpfad entfernen.
+  - Umsetzung: In `cmake/ModularBuild.cmake` die per-Source-Compile-Option fuer `monitoring_api_handler.cpp` und `index_api_handler.cpp` auf config-gated Debug-Only umgestellt (`/Od` nur fuer non-Release), bei Erhalt von `/bigobj` und `/Zm200`.
+  - Validierung: Re-Configure + Build (`CMake: Configure (windows-release)`, `CMake: Build (windows-release)`) ohne D9025-Treffer im Build-Log.
+
+- [x] QW-core-09: MSVC C1060 Heap-OOM im Monitoring-API-Compilepfad entschärfen.
+  - Umsetzung: In `cmake/CMakeLists.txt` die monolithischen Server-TUs `monitoring_api_handler.cpp` und `index_api_handler.cpp` zusätzlich mit `COMPILE_OPTIONS "/bigobj;/Zm200"` versehen und gleichzeitig aus Unity ausgeschlossen belassen.
+  - Validierung: `cmake --build --preset windows-release --target themis_network --parallel 16` erfolgreich; vorheriger C1060-Abbruch auf `monitoring_api_handler.cpp` trat nicht mehr auf.
+
+- [x] QW-core-10: Drei produktive Warnungs-Hotspots lokal bereinigt (`C4456`, `C4189`).
+  - Umsetzung: In `src/importers/federated_learning.cpp` inneres `sum` auf `trimmed_sum` umbenannt (kein Shadowing mehr), in `src/llm/lora_framework/lora_training_service.cpp` ungenutzte Variable `batches_per_epoch` entfernt, und in `src/index/vector_index.cpp` `vector_data` nur im tatsächlich benötigten Scope geführt.
+  - Validierung: `cmake --build --preset windows-release --target themis_network --parallel 16` erfolgreich (inkrementell) ohne die zuvor gemeldeten Warnstellen.
+
+- [x] QW-core-11: Signed/Unsigned-Vergleiche in Gossip-Update-Alterspfad bereinigt (`C4018`).
+  - Umsetzung: In `src/sharding/gossip_config_manager.cpp` `now_ns` an beiden relevanten Stellen explizit als `uint64_t` geführt (statt implizitem signed `count()`-Typ), um Vergleiche mit `timestamp_ns` robust und warnfrei zu machen.
+  - Validierung: `cmake --build --preset windows-release --target themis_network --parallel 16` ohne `C4018`-Treffer auf den zuvor gemeldeten Zeilen.
+
+- [x] QW-core-12: Narrowing im Robustness-Scoring entschärft (`C4244`).
+  - Umsetzung: In `src/rag/adversarial_tester.cpp` den `std::count_if`-Rückgabewert als `const auto` statt `long` geführt, damit keine implizite `__int64 -> long`-Konvertierung mehr erfolgt.
+  - Validierung: `cmake --build --preset windows-release --target themis_network --parallel 16` ohne `C4244`-Treffer auf der gemeldeten Stelle.
+
+- [x] QW-core-13: Generated shard-proto Headerwarnung (`C4267`) im Sharding-Modul gekapselt.
+  - Umsetzung: In `cmake/ModularBuild.cmake` für `themis_sharding` (nur MSVC, nur bei aktivem `themis_shard_proto`) gezielt `/wd4267` ergänzt, damit `shard_rpc.pb.h`-Narrowing nicht in Consumer-TUs streut.
+  - Validierung: `cmake --build --preset windows-release --target themis_network --parallel 16` ohne `C4267`-Treffer auf `shard_rpc.pb.h`.
+
+- [x] QW-core-14: `[[nodiscard]]`-Rückgaben von `freeGPU`/`freeCPU` explizit behandelt (`C4834`).
+  - Umsetzung: In `src/llm/active_vram_allocator.cpp` vier Best-Effort-Aufrufe von `gpu_mgr_->freeGPU/freeCPU` mit `static_cast<void>(...)` umschlossen; semantik ist bewusst fire-and-forget (Speicherfreigabe im VRAM-Allocator-Teardown).
+  - Validierung: Inkrementeller Build erfolgreich ohne C4834-Zeilen im Output.
+
+- [x] QW-core-15: Nicht referenzierte statische Helfer in WAL-Storage markiert (`C4505`).
+  - Umsetzung: In `src/storage/wal_storage.cpp` die vier bounds-safe Overloads (`encode_u32/u64`, `decode_u32/u64`) mit `[[maybe_unused]]` versehen, da sie in bestimmten Unity-Builds nicht referenziert werden.
