- API latency measurements for Whisper and Claude
- Audio hash-based duplicate detection
- Hallucination filtering with detailed logging
Changes:
- Add SessionLogger class for structured session data export

Document that the initial transcript analysis was done under degraded conditions (multiple voices, variable distances/volumes, poor mic) which may explain some of the segmentation issues.

Replace WAV with Opus encoding for Whisper API uploads:
- Add libopus & libogg via FetchContent (no vcpkg dependency)
- Implement AudioBuffer::saveToOpus() with Ogg container
- Configure Opus encoder for voice (VOIP mode, 32kbps VBR)
- Update WhisperClient to use Opus format (audio/ogg)
- Fix Windows temp file path compatibility
Benefits:
- 46x smaller files (37KB vs 1.7MB for 10s audio)
- Reduced API costs and bandwidth
- Faster uploads for real-time translation
- Whisper API fully supports Opus/Ogg format

PROBLÈME RÉSOLU: Les shaders ImGui compilent maintenant avec succès!
Changements majeurs:
- Remplacé vcpkg ImGui par FetchContent (compilation from source)
- Créé wrapper GLAD pour ImGui (imgui_opengl3_glad.cpp)
- Ajout de makeContextCurrent() pour gérer le contexte OpenGL multi-thread
- Release du contexte dans initialize(), puis rendu current dans uiThread()
Root Cause Analysis:
1. Rendering s'exécute dans uiThread() (thread séparé)
2. Contexte OpenGL créé dans thread principal n'était pas accessible
3. glCreateShader retournait 0 avec GL_INVALID_OPERATION (erreur 1282)
4. Solution: Transfer du contexte OpenGL du thread principal vers uiThread
Debugging profond:
- Ajout de logs debug dans ImGui pour tracer glCreateShader
- Découvert que handle=0 indiquait échec de création (pas compilation)
- Identifié erreur WGL \"ressource en cours d'utilisation\" = contexte locked
Fichiers modifiés:
- vcpkg.json: Supprimé imgui
- CMakeLists.txt: FetchContent pour ImGui + imgui_backends library
- src/imgui_opengl3_glad.cpp: Nouveau wrapper GLAD
- src/ui/TranslationUI.{h,cpp}: Ajout makeContextCurrent()
- src/core/Pipeline.cpp: Appel makeContextCurrent() dans uiThread()
- build/.../imgui_impl_opengl3.cpp: Debug logs (temporaire)
Résultat: UI fonctionne! NVIDIA RTX 4060 GPU, OpenGL 3.3.0, shaders compilent

Changes:
- Add GLAD dependency via vcpkg for proper OpenGL function loading
- Force NVIDIA GPU usage with game-style exports (NvOptimusEnablement)
- Create working console version (SecondVoice_Console.exe)
- Add dual executable build (UI + Console versions)
- Update to OpenGL 4.6 Core Profile with GLSL 460
- Add GPU detection and logging
- Fix GLFW header conflicts with GLFW_INCLUDE_NONE
Note: OpenGL shaders still failing to compile despite GLAD integration.
Console version is fully functional for audio capture and translation.
