[Suggestion] In ReadMe, How about add description of AvanteClear for whom suffered from prevented applying diff.

How about add description of AvanteClear to README file?

I've been suffered a few phenomenon like the below.

1. After ask result is completed, there isn't any hint was shown to apply the difference. ---> So I have no choice but to copy, then paste manually..
2. After suffering 1 issue a few days, suddenly the ask result is truncated before the full response was prompted.

I've searched the phenomenon in this repository's issue page, but failed to find out similar was reported, and also failed to find out some description in docs.

It was too tedious to tolerate this, So today I've done some testing, and concluded it is caused by accumulated history. And by after clear the history by using AvanteClear the phenomenon was gone!

So I suggested that add some description to README.md file to help people to suffer similar isssue.

(I am not sufficiently confident for my English skill, so I thought it is better to open discussion, than I make PR)

Thank you.
