Code Review

This pull request introduces a type_count field to SummaryModel to store raw counts of evaluation labels, separating them from the calculated type_ratio percentages. It also adds a helper method _refresh_type_ratio to compute ratios from counts. A review comment highlights a performance issue where _refresh_type_ratio is unnecessarily called inside a loop for every processed item, suggesting its removal since the ratio is already refreshed in summarize.

在列表分析咉合中，为每个处理的数据项都调用 self._refresh_type_ratio(self.summary) 会导致严重的性能问题。
_refresh_type_ratio 需要遍历所有的字段和标签来重新计算比例，其时间复杂度为 $O(\text{fields} \times \text{labels})$。在处理大量数据时，这会在主循环中引入不必要的计算开销。

实际上＀

1. write_single_data 并不依赖 type_ratio。
2. 每次写入 summary 时调用的 self.summarize(self.summary) 内部已经调用乆 _refresh_type_ratio。
3. 在 execute 结束时，也会调用 self.summarize 来生成最终的 summary。

因此，建议移除此处的 self._refresh_type_ratio(self.summary)。如果需要确保 get_summary() 随时获取最新的 type_ratio，可以在 get_summary() 方法中按需调用 _refresh_type_ratio。

Suggested change

	self.summary.score = round(
	self.summary.num_good / self.summary.total * 100, 2
	)
	self._refresh_type_ratio(self.summary)
	self.summary.score = round(
	self.summary.num_good / self.summary.total * 100, 2
	)
