📄 Description

Problem Fix

Previously, hovering the mouse over a chat item in the sidebar would automatically request and load the entire content of that chat (including all messages and base64 images). If a chat contained a large number of images, this would result in a significant amount of data being repeatedly transferred each time the hover occurred, greatly wasting bandwidth and impacting performance.

Main Changes

Removed the logic for automatically requesting full chat content on hover to prevent repeated large data transfers.
When dragging, only chat metadata (id, title) is passed, no longer the full chat object, further improving performance.
Maintained existing drag and drop and interaction functionalities.
Simplified state management, improving sidebar performance, especially beneficial for chats with numerous images.
Changed comments from Chinese to English for easier international collaboration.

Impact

Now, the full data is only fetched when truly needed (e.g., clicking to enter the chat or dragging), significantly improving efficiency and user experience.
