Feature request: Add a "Delete All Chats" / "Clear History" button to the sidebar

[maxkongerskov]

Hi team,

I really love the Unsloth Studio app! However, I have run into a usability issue regarding chat management.

The Problem:
When testing different prompts or having long sessions, the sidebar history becomes very cluttered very quickly (see screenshot below). Currently, there is no easy way to clean this up; I have to manually click into every single chat to delete them one by one.

Could you please add a "Delete All Chats" or "Clear History" button to the bottom of the sidebar menu?

I have attached an image showing exactly where I think this would fit best (marked with the red arrow). This would make managing the UI much cleaner and faster.

Thanks for the great work!
