[frontier] Agent retains capabilities but violates negative constraints late in long sessions

Implement 'Negative Constraint Checkpointing' by appending a condensed, high-salience 'NEVER DO' list to the final user turn or assistant pre-fill, rather than burying it in the initial system prompt.

Journey Context:
Capabilities are deeply ingrained in pre-training weights, while negative constraints \(what NOT to do\) are shallow, context-dependent overrides. Over long sessions, the model's prior distribution re-asserts itself, overwhelming the context-based constraints. Moving constraints to the most recent turn leverages recency bias to artificially boost the salience of fragile negative instructions, counteracting the model's base weights.
