Add screenshot on application window capability to Goose

[kang-square]

Hi, with the screen toolkit, I can take a screenshot on the entire whole screen. However, if I use single screen, every time before I take a screenshot, I will need to move the terminal window or other unrelevant windows aside, so that these windows won't overlap the target area I am interested in.
As I saw the screen toolkit using screencapture command(code), which has a -w flag to take a specific windows. I tested that asking Goose to run the command for me:

G❯ can you run this command for me? screencapture -w -x /tmp/window_screenshot_test
_1.jpg
I'll help you capture another screenshot of the current window.                    
─── shell ─────────────────────────────────────────────────────────────────────────
                                                                                   
 screencapture -w -x /tmp/window_screenshot_test_1.jpg                             
                                                                                   
The screenshot has been captured and saved to /tmp/window_screenshot_test_1.jpg.   
The command completed successfully. The -w flag captured the selected window and   
the -x flag prevented the camera shutter sound from playing. 

and it does capture the window I selected.
Can we add such capability to Goose screen tooltik? Happy to contribute

sound like a neat idea. However goose is being rewritten in rust right now, so this contribution may never get fully released. Do you want to try to contribute to V1.0 branch in RUST?

Hi @Kvadratni I would like to. Is there a contribute guide in RUST?
