Implement load image tool and fix media reference propagation

Implement load image tool and fix media reference propagation: a task in LegoFlow-SWE (Harbor dataset). Additionally, tool results that produce media references (e.g., media://... ) are not being propagated correctly. The tool loop discards the Media field from a tool result, so references…

The task

Additionally, tool results that produce **media references** (e.g., `media://...`) are not being propagated correctly. The tool loop discards the `Media` field from a tool result, so references generated by tools like `load_image` are never resolved into base64 image‑url parts for the next LLM request. Finally, the…
