    // Skip metadata and configuration entries
    if (key === '_metadata' || key === 'multi_ai_review_enabled' || key === 'primary_review_provider_id') {
      continue;
    }
    // Only include actual provider objects
    if (value && typeof value === 'object' && value.hasOwnProperty('enabled')) {
      providers.push(key);
    }
  }
  return providers;
}
```

## 📚 **Previous Release: v3.6.1 - REFACTOR: Comprehensive Hardcode Elimination & Central Configuration**
**Release Date:** July 14, 2025

### 🔧 **MAJOR REFACTOR: Enterprise-Grade Configuration Management**
**Problem Solved:** WOARU had scattered hardcoded values across the codebase making maintenance difficult and configuration inconsistent. Magic numbers, API URLs, and tool commands were duplicated throughout the code.

**Revolutionary Solution:**
- **🏗️ Complete Hardcode Elimination**:
  - All ESLint rules centralized (`no-var`, `eqeqeq`, etc.)
  - SOLID principle thresholds unified in central config
  - API endpoints for all LLM providers standardized
  - Tool commands (`npx eslint`, `npm run lint`) centralized
- **📋 Enhanced constants.ts Architecture**:
  - `ESLINT_RULES` - All linter rules in one place
  - `SOLID_THRESHOLDS` - Configurable complexity limits
  - `QUALITY_THRESHOLDS` - Adjustable quality standards
  - `TOOL_COMMANDS` - Standardized CLI commands
  - `API_ENDPOINTS` - Central API URL management
- **⚡ Maintenance Benefits**:
  - Single source of truth for all configuration values
  - Easy threshold adjustments without code changes
  - Consistent tool command usage across the codebase
  - Type-safe configuration with TypeScript support

### 🏗️ **Technical Implementation Examples**

**Before Refactoring (Scattered Hardcodes):**
```typescript
// ❌ Multiple files with hardcoded values
// CodeSmellAnalyzer.ts
rule: 'no-var'
severity: complexity > 15 ? 'error' : 'warning'

// SRPChecker.ts  
const thresholds = { low: 8, medium: 15, high: 25 };

// cli.ts
baseUrl: "https://api.anthropic.com/v1/messages"

// QualityRunner.ts
await execAsync(`npx eslint "${filePath}"`);
```

**After Refactoring (Centralized Configuration):**
```typescript
// ✅ Single source of truth in constants.ts
// All files now import from central config
rule: APP_CONFIG.ESLINT_RULES.NO_VAR
severity: complexity > APP_CONFIG.QUALITY_THRESHOLDS.COMPLEXITY_WARNING
const thresholds = APP_CONFIG.SOLID_THRESHOLDS.METHODS_PER_CLASS
baseUrl: APP_CONFIG.API.ANTHROPIC
await execAsync(`${APP_CONFIG.TOOL_COMMANDS.ESLINT.BASE} "${filePath}"`);
```

### 🎯 **Configuration Categories Centralized**
1. **ESLint Rules**: `NO_VAR`, `EQEQEQ`, `PREFER_CONST`, `NO_CONSOLE`
2. **SOLID Thresholds**: Method counts, line limits, parameter counts
3. **Quality Standards**: Complexity warnings, error thresholds
4. **Tool Commands**: NPM scripts, ESLint commands, Prettier commands  
5. **API Endpoints**: All LLM provider URLs centralized

## 📚 **Previous Release: v3.6.0 - AI-Powered Code Documentation System**

### 💡 **Real-World Examples**

**Human-Friendly Documentation (`nopro`):**
```javascript
// Explain-for-humans: This function calculates the total cost including tax for customer purchases.
function calculateTotal(items, taxRate) {
  const subtotal = items.reduce((sum, item) => sum + item.price, 0);
  const tax = subtotal * taxRate;
  return subtotal + tax;
}
```

**Technical Documentation (`pro`):**
```javascript
/**
 * Calculates the total cost including tax for a collection of items
 * 
 * @param {Array<Object>} items - Array of items with price property
 * @param {number} taxRate - Tax rate as decimal (e.g., 0.08 for 8%)
 * @returns {number} Total cost including tax
 * @example
 * // Calculate total for $100 worth of items with 8% tax
 * const total = calculateTotal([{price: 100}], 0.08); // returns 108
 */
function calculateTotal(items, taxRate) {
  const subtotal = items.reduce((sum, item) => sum + item.price, 0);
  const tax = subtotal * taxRate;
  return subtotal + tax;
}
```

### 🎯 **Usage Examples**
```bash
# Generate human-friendly documentation for uncommitted changes
woaru docu nopro --local

# Generate technical documentation for all files in src/
woaru docu pro --path-only src/

# Preview documentation changes before applying
woaru docu nopro --git main --preview
