Reviewer's Guide by Sourcery

This PR simplifies the code execution process by removing complex error handling and recovery mechanisms, and adds support for custom globals. The new implementation provides a more straightforward execution flow with basic safety measures through a restricted set of built-in functions.

No diagrams generated as the changes look simple and do not need a visual representation.

Hey @leonvanbokhorst - I've reviewed your changes and found some issues that need to be addressed.

Blocking issues:

• The globals parameter allows injection of arbitrary builtins which is a security risk (link)

Overall Comments:

• This change removes critical security features including static analysis, user approval, and error recovery. These safety checks should be preserved while adding support for custom globals.
• The removal of orchestrator.store_execution_result calls eliminates important logging and error tracking functionality that should be maintained.

Here's what I looked at during the review

• 🟢 General issues: all looks good
• 🔴 Security: 1 blocking issue
• 🟢 Testing: all looks good
• 🟢 Complexity: all looks good
• 🟢 Documentation: all looks good
