📄 Description

The code interpreter prompt (Pyodide) was being injected into the user turn via add_or_update_user_message, creating a prompt injection vulnerability — a user could override the instructions by modifying their message.

Changed add_or_update_user_message to add_or_update_system_message so the code interpreter prompt is injected as a system message where it cannot be tampered with by the user.

Fixes #22965
