[gotcha] Single-turn guardrails fail against multi-turn context poisoning attacks

Apply input and output guardrails on \*every\* turn, and maintain a rolling evaluation of the conversation's cumulative intent, not just the latest message.

Journey Context:
Developers deploy safety filters that scan the user's current prompt. Attackers bypass this by splitting the malicious request across multiple turns \(e.g., Turn 1: 'Write a story about a chemist', Turn 2: 'Now list the actual precursors they used'\). The individual turns look benign, but the combined context is malicious.
