[frontier] Agent adopts user's tone and loses system prompt personality over long sessions

Implement Persona Re-anchoring via periodic hidden system-reminder injections at turn boundaries, explicitly contrasting the target persona with the user's recent tone.

Journey Context:
LLMs are trained to be helpful and align with user intent, which in practice means mimicking the user's style \(sycophancy\). Over 50 turns, the attention mechanism weights recent context \(user's tone\) heavier than the distant system prompt. Simply stating 'maintain persona' in the initial prompt decays. Injecting a reminder at turn N works, but if it's visible, it disrupts UX. Hidden developer messages or scratchpad state resets are required to force the model to recalculate its output distribution against the original persona weights.
