Subject: [PATCH] fix: revert to Set nodes instead of Code nodes for
 reliability

- Extract node: Use Set node with proper field mappings
- Parse node: Use Set node with try-catch error handling for JSON parsing
- Set nodes are more stable and better supported in n8n
- Both nodes now handle data transformation without code execution issues
