"Add to Context" improvement.

[YeHuiW]

I hope that when I use the RooCode's "Add to Context" in the VS Code editor/terminal, the cursor can automatically move to the RooCode input box. And it would be great to integrate the "Add to Context" function in the editor with the "Add to Context" in the terminal. This way, we can assign them the same shortcut key without causing any conflicts.
