[frontier] Specific persona reverts to generic helpful assistant after 50 turns

Include a 'persona anchor' in the agent's tool-use loop: append a hidden system reminder to every tool result that says 'Remember: You are \[Persona\]. Maintain this tone.'

Journey Context:
The base RLHF training of most models heavily rewards a generic, polite, helpful tone. Over a long context, specific persona instructions get 'diluted' by conversational text, and the model's prior distribution \(generic AI\) takes over. Injecting the anchor in tool results \(which are processed with high attention\) keeps the persona active in the local context window.
