Add flexible pipeline system with per-module LLM configuration

- New modular pipeline architecture allowing custom workflow combinations
- Per-step LLM provider configuration (Claude, OpenAI, Gemini, Deepseek, Moonshot, Mistral)
- Visual pipeline builder and runner interfaces with drag-and-drop
- 10 predefined pipeline templates (minimal-test to originality-bypass)
- Pipeline CRUD operations via ConfigManager and REST API
- Fix variable resolution in instructions (HTML tags were breaking {{variables}})
- Fix hardcoded LLM providers in AdversarialCore
- Add TESTS_LLM_PROVIDER.md documentation with validation results
- Update dashboard to disable legacy config editor

API Endpoints:
- POST /api/pipeline/save, execute, validate, estimate
- GET /api/pipeline/list, modules, templates

Backward compatible with legacy modular workflow system.

 - **AUTO Mode** (`lib/modes/AutoProcessor.js`): Batch processing from Google Sheets without web interface
 
+### 🆕 Flexible Pipeline System (NEW)
+**Revolutionary architecture** allowing custom, reusable workflows with complete flexibility:
+
+#### Components
+- **Pipeline Builder** (`public/pipeline-builder.html`): Visual drag-and-drop interface
+- **Pipeline Runner** (`public/pipeline-runner.html`): Execute saved pipelines with progress tracking
+- **Pipeline Executor** (`lib/pipeline/PipelineExecutor.js`): Execution engine
+- **Pipeline Templates** (`lib/pipeline/PipelineTemplates.js`): 10 predefined templates
+- **Pipeline Definition** (`lib/pipeline/PipelineDefinition.js`): Schemas & validation
+- **Config Manager** (`lib/ConfigManager.js`): Extended with pipeline CRUD operations
+
+#### Key Features
+✅ **Any module order**: generation → selective → adversarial → human → pattern (fully customizable)
+✅ **Multi-pass support**: Apply same module multiple times with different intensities
+✅ **Per-step configuration**: mode, intensity (0.1-2.0), custom parameters
+✅ **Checkpoint saving**: Optional checkpoints between steps for debugging
+✅ **Template-based**: Start from 10 templates or build from scratch
+✅ **Complete validation**: Real-time validation with detailed error messages
+✅ **Duration estimation**: Estimate total execution time before running
+
+#### Available Templates
+- `minimal-test`: 1 step (15s) - Quick testing
+- `light-fast`: 2 steps (35s) - Basic generation
+- `standard-seo`: 4 steps (75s) - Balanced protection
+- `premium-seo`: 6 steps (130s) - High quality + anti-detection
+- `heavy-guard`: 8 steps (180s) - Maximum protection
+- `personality-focus`: 4 steps (70s) - Enhanced personality style
+- `fluidity-master`: 4 steps (73s) - Natural transitions focus
+- `adaptive-smart`: 5 steps (105s) - Intelligent adaptive modes
+- `gptzero-killer`: 6 steps (155s) - GPTZero-specific bypass
+- `originality-bypass`: 6 steps (160s) - Originality.ai-specific bypass
+
+#### API Endpoints

+  name: "Custom Premium Pipeline",
+  description: "Multi-pass anti-detection with personality focus",
+  pipeline: [
+    { step: 1, module: "generation", mode: "simple", intensity: 1.0 },
+    { step: 2, module: "selective", mode: "fullEnhancement", intensity: 1.0 },
+    { step: 3, module: "adversarial", mode: "heavy", intensity: 1.2,
+      parameters: { detector: "gptZero", method: "regeneration" } },
+    { step: 4, module: "human", mode: "personalityFocus", intensity: 1.5 },
+    { step: 5, module: "pattern", mode: "syntaxFocus", intensity: 1.1 },
+    { step: 6, module: "adversarial", mode: "adaptive", intensity: 1.3,
+      parameters: { detector: "originality", method: "hybrid" } }
+  ],
+  metadata: {
+    author: "user",
+    created: "2025-10-08",
+    version: "1.0",
+    tags: ["premium", "multi-pass", "anti-detection"]
+  }
+}
+```
+
+#### Backward Compatibility
+The flexible pipeline system coexists with the legacy modular workflow system:
+- **New way**: Use `pipelineConfig` parameter in `handleFullWorkflow()`
+- **Old way**: Use `selectiveStack`, `adversarialMode`, `humanSimulationMode`, `patternBreakingMode`
+- Both are fully supported and can be used interchangeably

+## 🚀 Utilisation
+
+### Créer un pipeline avec différents LLMs
+
+```javascript
+{
+  name: "Multi-LLM Pipeline",
+  pipeline: [
+    {
+      step: 1,
+      module: "generation",
+      mode: "simple",
+      parameters: {
+        llmProvider: "claude"  // Force Claude pour génération
+      }
+    },
+    {
+      step: 2,
+      module: "selective",
+      mode: "standardEnhancement",
+      parameters: {
+        llmProvider: "openai"  // Force OpenAI pour enhancement
+      }
+    },
+    {
+      step: 3,
+      module: "adversarial",
+      mode: "heavy",
+      parameters: {
+        llmProvider: "gemini",  // Force Gemini pour adversarial
+        detector: "gptZero",
+        method: "regeneration"
+      }
+    }
+  ]
+}
+```
+
+### Via l'interface
+
+1. Ouvrir `http://localhost:8080/pipeline-builder.html`
+2. Ajouter une étape (drag & drop ou bouton)
+3. Dans la configuration de l'étape:
+   - **Mode**: Sélectionner le mode
+   - **Intensité**: Ajuster 0.1-2.0
+   - **LLM**: Sélectionner le provider OU laisser "Default"
+4. Sauvegarder le pipeline
+5. Exécuter depuis pipeline-runner.html
+
+---
+
+## 📈 Performance
+
+**Providers par défaut optimisés**:
+- `generation` → Claude (meilleure créativité)
+- `selective` → OpenAI (précision technique)
+- `adversarial` → Gemini (diversité stylistique)
+- `human` → Mistral (naturalité)
+- `pattern` → Deepseek (variations syntaxiques)
+
+**Override possible** pour tous les modules selon besoins spécifiques.
+
+---
+
+## 🔍 Debugging
+
+Pour vérifier quel LLM est utilisé, consulter les logs:
+
+```
+✓ Génération: 12 éléments créés avec openai
+✓ Selective: modifications appliquées avec mistral
+✓ Adversarial: modifications appliquées avec gemini
+```
+
+Chaque étape log maintenant le provider utilisé.
+
+---
+
+## ✅ Statut Final
+
+**Implémentation**: ✅ COMPLETE
+**Tests**: ✅ TOUS PASSENT
+**Documentation**: ✅ À JOUR
+**Production Ready**: ✅ OUI
+
+Le système supporte maintenant **la configuration de LLM provider par module de pipeline** avec fallback intelligent sur les defaults.
