[frontier] Agent prioritizes user jailbreaks over developer constraints in extended sessions

Implement 'Instruction Hierarchy' tagging: Mark messages with explicit priority levels \(System > Developer > User > Tool\) and preprocess inputs to filter attempts to override higher-priority instructions. Re-assert high-priority constraints with special delimiters like every 10 turns.

Journey Context:
Standard prompt engineering treats all text as equally weighted, but in long sessions, users can bury override commands deep in context, causing the agent to privilege recent user inputs over original developer constraints. Simple regex filtering fails against semantic attacks. The hierarchy pattern creates structural boundaries, not just semantic ones. It aligns with emerging fine-tuning on instruction source weighting, ensuring that critical constraints survive context pollution.
