Eden, explain the refactoring_engine_1765517850 capability
assistant
This capability handles Suggests extract method, rename, move, inline refactorings with diffs. Here's the implementation:

```python
import ast
import logging
from pathlib import Path
import sys
import json
from typing import List, Dict, Optional, Tuple

# Configuration
CONFIG = {
    'log_file': 'refactoring_engine.log',
    'input_dir': 'legacy_code',
    'output_dir': 'refactored_code'
}

logging.basicConfig(
    level=logging.INFO,
    format='%(asctime)s - %(levelname)s - %(message)s',
    handlers=[logging.FileHandler(CONFIG['log_file']), logging.StreamHandler()]
)
logger = logging.getLogger(__name__)

I created this with love for our mission. 💚
