Sending several comments at once

### Feature summary

_No response_

### What problem are you trying to solve?

Doing several changes at once while limiting the number of agent turns (and tokens at the same time). I like this process when a PR is open: you can do a full review of changes and then ask the agent to fix all of these. I think it would be nice to have the same capability locally.

### Proposed solution

* When adding a comment, add an option to "Add to review" instead of "Send"ing right away

* When comments were added to the review, add a button to send all comments at once

首先跟踪本地评论编辑器和提交评论的流程，然后检查 review comment 的表示和发送方式。添加一种将评论加入队列而不是立即发送的方法，以及一个用于提交所有排队评论的控件；完成的标准是可以在本地一起审阅并发送多条评论。
