Três camadas de proteção contra runaway token burn no AgentRunnerService:
1. MAX_TURNS_PER_MESSAGE = 15
Cap dentro de uma única chamada run(). Já estava aplicado;
agora extraído como constante nomeada.
2. MAX_TURNS_PER_CONVERSATION = 30
Cap ao longo da vida da conversa. Contador em
conversation.custom_attributes['captain_turn_count']. Ao atingir,
dispara bot_handoff automático e responde com mensagem de
transferência pra humano.
3. TOOL_LOOP_THRESHOLD = 3
Detecta a mesma (tool_name, args) invocada 3+ vezes no resultado
de um único run (sintoma do loop faq_lookup que queimou tokens
em 2026-04-19). Ao detectar: dispara bot_handoff e aborta o turno.
trigger_bot_handoff! aciona conversation.bot_handoff! quando
disponível, removendo a conversa do pipeline automático.
Motivação: dois incidentes reais de queima de crédito OpenAI em
2026-04-19. Ver memory/feedback_never_touch_captain_without_safety_caps.md
pras invariantes completas.
Tests atualizados: mock_result agora stuba :messages (usado pelo
novo tool_loop_detected?) e max_turns esperado é 15.
