feat: detect plural/group-addressed questions to trigger all-agent responses

Se añade detección de preguntas dirigidas al grupo en los prompts de routing
y quality. Cuando el usuario usa plural o se dirige colectivamente a los
agentes ("¿qué opinan?", "chicos", "hey everyone", etc.), el routing baja
la confianza a 0.2 y el evaluador de calidad mantiene continue=true hasta
que todos los agentes hayan participado.

Esto garantiza que preguntas con intención grupal reciban respuestas de
todos los agentes disponibles, no solo del más relevante.

 - Score 0.7-0.85: Solid multi-agent response. Continue only if there's a clear gap.
 - Score 0.85+: Comprehensive answer with multiple perspectives covered. Set "continue": false.
 
+PLURAL / GROUP ADDRESS RULE:
+If the original question addresses the group collectively (e.g., "¿qué opinan?", "chicos", "¿alguien sabe...?", "what do you all think?", "hey everyone", "guys", "team") or uses plural pronouns/verbs directed at agents, the conversation MUST continue until every available agent has contributed at least once. Score should stay below 0.5 and "continue" must be true until all agents have responded.

 IMPORTANT: Err on the side of continuing. Multi-agent collaboration produces better results. Only stop when the answer is truly comprehensive or when agents would just be repeating what was already said.

 - Keep confidence LOW (0.3-0.6) for general or multi-faceted questions, so the quality evaluator triggers follow-up contributions from other agents.
 - Only use high confidence (0.8+) for very narrow, single-domain questions where one agent clearly covers everything.
