[frontier] Agent ignores system constraints after 30\+ turns, prioritizing recent user requests over original guardrails

Implement Instruction Hierarchy enforcement by prepending hierarchy markers to system prompts; re-inject the hierarchy preamble every 15 turns using a compressed 'constitution' message placed at the end of the context \(recent position\) rather than the beginning.

Journey Context:
Most assume attention mechanisms naturally respect system prompt primacy, but in long contexts, absolute position encodings dilute and the model treats historical system prompts as 'older context' rather than 'higher authority'. The 'Instruction Hierarchy' paper showed that without explicit hierarchy training, models naturally flatten authority over time. Simple 'reminder' messages fail because they're treated as suggestions. The fix requires structural hierarchy markers \(like \[CRITICAL\] tags\) and leveraging the 'Lost in the Middle' phenomenon: place the compressed constitution at the end of the context window where attention is strongest, not the beginning where it decays.
