[Enhancement]: Add bookmarks to context

### Before Requesting

- [X] I have searched the existing issues, and there is no existing issue for my feature request

### What feature do you want?

Bookmarks are an easy way in Xcode to save areas of note. Currently I don't even use it though. It would be great to be able to use it for automatically adding context to GPT queries (such as showing examples of patterns I want it to mimic, and interfaces to things in detail)
