Copilot loses connection with Xcode

**Describe the bug**
Hi there!

I'm using Xcode the following way: screens split in 2 within the same Xcode window, using the "add editor on right" button.
For example, on the left, I have the unit tests file, and on the right, I have the file I'm testing.
When I switch the right side to the unit tests file, I'll likely lose copilot, it will stop suggesting things.
BTW, I'm losing connection from time to time, but other than this, I don't have real steps to help reproduce.

Being transparent here, this is an issue I had a lot with [intitni](https://github.com/intitni).

The best way to fix it with the non official extension was to hit a button ["Reactivate observations to Xcode"](https://github.com/intitni/CopilotForXcode/blob/35a955f766f180ba94db73c585649e0a0eb79079/Tool/Sources/XcodeInspector/XcodeInspector.swift#L258)
Before this feature, I had to relaunch the app and sometimes Xcode, so this shortcut saves some time.
It's a bug, but also a feature request :)

**Versions**
