[frontier] Agent retains behaviors from a previous persona after a mid-session role switch

When changing agent personas mid-session, perform a Context Scrub by explicitly summarizing the previous persona's termination and injecting a hard delimiter \(e.g., \) before defining the new persona.

Journey Context:
LLMs do not have a reset button within a single session. If an agent acts as a 'Planner' and then is told 'now act as a Coder', it will code with the cautious, verbose style of a Planner. The context contains the residue of the old role. A simple instruction change isn't enough; you must explicitly mark the end of the old persona and the start of the new one, treating the context window like a state machine with explicit transitions.
