ActiveSession now has a 'responder lifetime that encodes whether responders are still active. This prevents calling proxy_remaining_messages() on sessions from run_session() where responders would die on return. New APIs: - ActiveSession::response() - builds NewSessionResponse for forwarding - ActiveSession::proxy_remaining_messages() - only on 'static sessions - SessionBuilder::spawn_session_proxy() - convenience for inject + proxy Removed SessionBuilder::proxy_session() which was an anti-pattern that combined too many concerns. Updated cookbook with both simple (spawn_session_proxy) and advanced (spawn_session + proxy_remaining_messages) patterns.
