"""#89161: a routed multiplex profile's personality must reach its turns.

``GatewayRunner`` used to snapshot ``_ephemeral_system_prompt`` once at boot
from the launch profile's config and hand that string to every routed turn,
so a secondary profile's ``display.personality`` / ``agent.system_prompt`` never
injected. ``_get_system_prompt_for_channel`` now resolves from the config of
the profile currently in scope (``run_sync`` runs inside
``_profile_runtime_scope``).
