Any plans for a Plugin System?

### **Is your feature request related to a problem? Please describe.**
I would like to have additional features on top of gitui, like aicommits or gitcliff support, perhaps a worktree plugin etc. Which don't seem to make sense as gitui core features, so I am thinking if a plugin system is under consideration or already in place.
Perhaps even integration with other editors or utilities.

### **Describe the solution you'd like**
A simple plugin system to allow for faster development "around" gitui without interfering with the core of the language itself.

### **Describe alternatives you've considered**
Adding all of the features to gitui itself which maybe a question for the maintainers to answer.

### **Additional context**
None, really love the project and lots of thanks from me. :)
