[agent\_craft] Prompt injection attacks override system prompts via jailbreaking or malicious user input

Use the 'developer' message role \(instead of 'system'\) for instructions that must remain immutable, ensuring the model treats these as high-privilege constraints that cannot be overridden by user content

Journey Context:
Traditional system prompts are supposed to set hard constraints, but adversarial users can often override them with 'ignore previous instructions.' The o1 model series introduces a strict hierarchy where the 'developer' message is treated as privileged metadata about the application's behavior, conceptually distinct from the conversation. The hard-won insight is that this is not just a rename: the model architecture explicitly weights developer messages as non-negotiable context, whereas system messages might be treated as part of the prompt string that the user can manipulate. This distinction is critical for security boundaries.
