feat: Add GLAD OpenGL loader and NVIDIA GPU forcing

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.

+# SecondVoice - Windows Build Guide
+
+## Status
+
+✅ **Build réussi** - L'application compile et s'exécute
+⚠️ **Problème GPU** - Utilise le GPU AMD intégré au lieu du NVIDIA RTX 4060
+
+## Ce qui fonctionne
+
+- ✅ Compilation MinGW sans Visual Studio
+- ✅ Chargement de la configuration (config.json)
+- ✅ Initialisation de PortAudio (capture audio)
+- ✅ Création de la fenêtre GLFW
+- ✅ Pipeline de traduction démarré
+- ✅ Build statique (exe standalone de 6.5 MB)
+
+## Problème actuel : Shaders OpenGL
+
+Les shaders GLSL ne compilent pas car Windows utilise le **GPU AMD intégré** au lieu du **NVIDIA RTX 4060**.
+
+### Diagnostic
+
+Lancez `test_opengl.exe` dans `build\mingw-Release\` pour voir quel GPU est utilisé :
+
+```bash
+cd build\mingw-Release
+test_opengl.exe
+```
+
+Résultat actuel : **AMD Radeon Graphics** (devrait être NVIDIA GeForce RTX 4060)
+
+## Solutions
+
+### Solution 1: Lancer depuis Windows (pas depuis bash)
+
+**Le GPU NVIDIA ne sera utilisé que si vous lancez depuis Windows natif, pas depuis bash/terminal.**
+
+Double-cliquez sur le **raccourci "SecondVoice" sur votre bureau** créé automatiquement.
+
+OU allez dans l'explorateur Windows :
+```
+C:\Users\alexi\Documents\projects\secondvoice\build\mingw-Release\SecondVoice.exe
+```
+
+### Solution 2: Configuration Windows manuelle
+
+Si le problème persiste :
+
+1. **Windows Settings** (Win + I)
+2. **Système** → **Affichage** → **Graphiques**
+3. Cliquez **Parcourir** et sélectionnez :
+   ```
+   C:\Users\alexi\Documents\projects\secondvoice\build\mingw-Release\SecondVoice.exe
+   ```
+4. Cliquez **Options** → **Hautes performances**
+5. **Enregistrer**
+
+### Solution 3: NVIDIA Control Panel
+
+1. Clic droit sur le bureau → **Panneau de configuration NVIDIA**
+2. **Gérer les paramètres 3D** → **Paramètres du programme**
+3. **Ajouter** → Sélectionnez `SecondVoice.exe`
+4. **Processeur graphique** → **NVIDIA haute performance**
+5. **Appliquer**
+
+## Build
+
+### Rebuild complet
+
+```bash
+.\build_mingw.bat --clean
+```
+
+### Build incrémental
+
+```bash
+.\build_mingw.bat
+```
+
+### Configuration GPU (déjà fait)
+
+```bash
+powershell -ExecutionPolicy Bypass -File set_gpu.ps1
+```
+
+## Prérequis pour exécution
+
+1. **Clés API** dans `.env` :
+   ```
+   OPENAI_API_KEY=sk-...
+   ANTHROPIC_API_KEY=sk-ant-...
+   ```
+
+2. **Microphone** connecté
+
+3. **config.json** (copié automatiquement dans build/)
+
+## Fichiers importants
+
+- `build\mingw-Release\SecondVoice.exe` - Exécutable principal (6.5 MB)
+- `build\mingw-Release\test_opengl.exe` - Outil de diagnostic GPU
+- `build\mingw-Release\config.json` - Configuration
+- `build\mingw-Release\.env` - Clés API (à créer)
+
+## Scripts utiles
+
+- `build_mingw.bat` - Build l'application
+- `set_gpu.ps1` - Configure le GPU NVIDIA
+- `create_shortcut.ps1` - Crée un raccourci bureau
+- `run_secondvoice.bat` - Lance l'application
