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
• Framework-specific analysis
• Adaptive remediation recommendations
• Cross-framework consistency checks

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
• No permanent artifacts
• Safe for live servers
