## KEY FEATURES IMPLEMENTED

### 1. Intelligent Remediation Engine ✅
- Context-aware recommendations (not generic advice)
- Specific commands for each issue type
- Severity classification (CRITICAL/WARNING/INFO)
- Color-coded terminal output
- Performance impact estimates

**Example Output:**
```
REMEDIATION: Disable WP_DEBUG in Production
  Current: WP_DEBUG is enabled in wp-config.php
  Impact: 10-15% performance penalty from error logging
  
  Fix:
    1. Edit /home/{user}/public_html/wp-config.php
    2. Change: define('WP_DEBUG', true);
    3. To: define('WP_DEBUG', false);
    4. Delete debug.log: rm wp-content/debug.log
    
  Expected Improvement: 10-15% faster page load
```

### 2. Performance Scoring System ✅
- A-F letter grades based on issue count
- Quantified critical and warning counts
- Color-coded severity indicators
- Overall performance assessment

### 3. Multi-Framework Support ✅
- Automatic framework detection

### 4. Error Handling ✅
- Graceful degradation when components unavailable
- Safe database access with error checking
- Timeout protection on external calls
- Informative error messages

### 5. Production Safety ✅
- Read-only analysis (no modifications)
- Temporary file cleanup on exit
