HandleFailure 实现 SupervisorStrategy

(system *System, child *PID, msg Message, err any)

// HandleFailure 实现 SupervisorStrategy
func (s *CompositeStrategy) HandleFailure(system *System, child *PID, msg Message, err any) any {
	// 尝试匹配错误类型
	if e, ok := err.(error); ok {
		errType := e.Error()
		if strategy, found := s.strategies[errType]; found {
			return strategy.HandleFailure(system, child, msg, err)
		}
	}

	// 使用回退策略
	return s.fallback.HandleFailure(system, child, msg, err)
}
