- Introduced a new contract for script returns, requiring an object with `output`, `context`, and `skipRemaining` fields. - Refactored existing scripts to align with the new return structure, ensuring compatibility with the updated context management. - Added utility functions for normalizing context and step results, improving the handling of script execution context. - Updated various scripts (e.g., fetch-binary, fetch-html, fetch-http) to return structured output and context, enhancing data flow and usability. - Improved error handling for script returns, ensuring clearer feedback when invalid structures are returned. This update significantly enhances the flexibility and clarity of script interactions within workflows.
