feat: anadir comando !metrics para metricas agregadas del dia actual

Implementa el comando built-in !metrics que lee los JSONL logs del dia actual usando shell/logger/query.go y calcula agregados en memoria: - Mensajes recibidos (handling event) - Comandos ejecutados (command_received) - Llamadas LLM (count, tokens totales, latencia media) - Llamadas a tools (count, errores) - Errores totales (nivel ERROR) - Total de entradas de log El comando se registra como built-in disponible para todos los agentes. Recibe logDir via Option pattern (WithLogDir) para no romper la firma de agents.New(). El launcher pasa logDir al crear cada agente. Formatea la salida como tabla markdown para Matrix. Incluye tests unitarios con logs JSONL sinteticos. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
