[Bug] 更改书籍名称后，导入MyClipping重复创建新书籍 📚❌

[mnyon]

Hi,尊敬的开发者,感谢你开发的KindleMate2,它解决了我对Kindlemate不再维护而我还有大量Kindle产生的标注可能会无处存放的忧虑.

我在使用这个软件的过程中发现了一个可能的逻辑不太符合直觉的行为,具体的描述如下:

📝问题描述:
在运行软件时，如果对已导入的书籍进行重命名，软件会重复创建新的书籍条目。这个问题在2025年1月20日的仓库代码（debug模式）中发现。

📝问题复现:
首先导入一次Kindle剪藏,这个时候对其中一本书进行重命名.

经过重命名后在Kindle中对一本书籍再次添加新的标注,这个时候再次导入就会导致重复出现一本书.但是新创建的书籍不会重复已经导入的.

🎉预期行为:最好的行为结果是当导入的书籍被更改名称了,那么下次导入的时候最好还可以导入到经过改名后的书籍中.

因为如果一本书被更名了,那很可能因为那本书名称过长,我想这可能是整理标注的过程中会用的一个功能.(因为改书名的另一个目的可能是保持引用一段书摘时正确且简洁的书名,这对于卡片写作的人会有些意义)

再次感谢作者的辛勤工作和KindleMate2.🙏

[English describtion - AIGC Created]
Hi, dear developer, thank you for developing KindleMate2. It has alleviated my concern about KindleMate no longer being maintained and my large number of Kindle highlights potentially having nowhere to be stored.
During my use of this software, I have discovered a behavior that may not be logically appropriate. Here is the specific description:

📝 Problem Description:
When running the software, if a book that has already been imported is renamed, the software will create a new book entry repeatedly. This issue was discovered in the repository code on January 20, 2025 (debug mode).

📝 Problem Reproduction:
First, import Kindle clippings and rename one of the books at this time.

After renaming, add new highlights to the book in Kindle. When importing again, the book will appear repeatedly. However, newly created books will not duplicate those already imported.

🎉 Expected Behavior: The best outcome would be that if an imported book is renamed, the next import should still be able to go into the renamed book.
This is because if a book is renamed, it is likely due to its long title.

I think this might be a feature used during the organization of highlights (since another reason for renaming a book might be to keep the title accurate and concise when citing a book excerpt, which could be meaningful for those who write on index cards).

Thank you again for your hard work and KindleMate2. 🙏
