Subject: [PATCH] Add GitHub App credentials test without sensitive data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## 🧪 Test GitHub App Credentials (Safe Version)

### Problem
Need to test if the GitHub App credentials are valid without exposing sensitive information.

### Solution
- ✅ **Safe credentials test**: Test GitHub App credentials using environment variables only
- ✅ **No sensitive data**: No hardcoded private keys or secrets
- ✅ **Environment analysis**: Analyze environment variables and their format
- ✅ **Step-by-step testing**: Test app auth creation and token generation

### Technical Changes

#### **Safe GitHub App Credentials Test Endpoint**
```javascript
// /api/test/github-app-credentials.js
- Tests with environment variables only
- Analyzes App ID and private key format
- Tests app auth creation and token generation
- Provides detailed analysis without exposing sensitive data
```

#### **Comprehensive Testing**
1. **Environment Analysis**: Check App ID and private key format
2. **Test 1**: Create app auth with environment variables
3. **Test 2**: Get app token with environment variables

### Files Added
- `api/test/github-app-credentials.js` - Safe GitHub App credentials test endpoint

### Impact
- 🧪 **Tests** GitHub App credentials safely using environment variables
- 🔍 **Analyzes** environment variable format and structure
- 📊 **Validates** if the credentials work without exposing sensitive data
- 🛠️ **Identifies** if the issue is with credentials or code logic

### Testing
- [x] Added safe GitHub App credentials test
- [x] Uses environment variables only
- [x] No sensitive data exposed
- [x] No linting errors
