Perform a comprehensive code review with the following analysis:

Changed files:
$CHANGED_FILES

Please analyze:
1. **Security Issues** - Check for vulnerabilities, hardcoded secrets, injection risks
2. **Performance** - Identify bottlenecks, N+1 queries, inefficient algorithms
3. **Code Quality** - Design patterns, SOLID principles, maintainability
4. **Testing** - Missing tests, edge cases not covered
5. **Breaking Changes** - API compatibility, database migrations needed

For each issue found, provide:
- Severity: Critical/High/Medium/Low
- File and line number
- Specific fix recommendation
- Example code if applicable

Format as JSON with structure:
{
  "summary": "overall assessment",
  "metrics": {
    "security_score": 0-100,
    "quality_score": 0-100,
    "test_coverage_impact": "estimated %"
