Feature Request: Add "Close All Tabs" functionality

Currently, users need to close each tab individually which can be time-consuming when working with multiple designs. It would be helpful to have a way to close all tabs at once.

Current Behavior

• Must close each tab manually by clicking the 'x' button
• No shortcut or bulk action available

Requested Features

1. Add "Close All Tabs" option to tab bar context menu (right-click)
2. Add keyboard shortcut for closing all tabs
3. Optional: Add "Close All But Current" option
