Nuevo paquete shell/logger/ que implementa logging estructurado JSONL para agentes. Incluye DailyRotatingWriter con rotación diaria y por tamaño (50MB default), limpieza automática de archivos viejos (7 días), compresión gzip de logs rotados, y funciones de consulta (ReadLogs, SearchLogs, ListAgents, ListDates) para que agentes LLM puedan leer logs de otros agentes. Basado en log/slog de stdlib, sin dependencias externas. 18 tests unitarios cubren rotación, concurrencia y consultas. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
