[frontier] Instruction Temporal Decay: Agents treat older instructions as deprecated compared to recent suggestions

Implement Temporal Tagging with Schema Enforcement: prefix every permanent instruction with a \[PERMANENT:ISO8601\] tag and enforce that the agent's output JSON includes a compliance\_check field referencing the timestamp of the constraints it followed.

Journey Context:
Models implicitly weight instructions by recency due to autoregressive nature. A constraint given at turn 1 has 'faded' by turn 50. Teams try occasional 'reminders,' which is ad-hoc. Temporal Tagging formalizes persistence into a protocol where the prompt construction layer \(not the LLM\) manages constraint validity. By forcing the model to output the timestamp of the constraints it used \(via structured output\), you create an audit trail that prevents the model from 'pretending' it forgot the constraint.
