Keep mode and approval state in the compact request-time runtime prompt, and stop repeating the long human mode description in every turn_meta block. The active user message still carries date, routed model, auto-route, reasoning, and working-set metadata.
This keeps the prompt envelope quieter while preserving the runtime-policy pointer used for cache-stable mode switches.
