* 🤖 AI Code Review - 2025 Standards
*
* This script demonstrates the 2025 approach where AI performs comprehensive
* code reviews automatically. In a full implementation, this would use Claude
* or GPT-4 to analyze code changes and provide detailed feedback.
*
* Current implementation: Basic analysis framework
* Future: Full AI-powered code review with suggestions
