Code version management

Is your feature request related to a problem? Please describe.
When models edit a particular piece of code, there is a chance that harmful changes may be inadvertently made to the code. Oddly enough, this disease can affect even people. This is partly why tools like difftools\were created. They can be used to carefully review all changes before committing, and then confirm or reject them.

Describe the solution you'd like
A clear and concise description of what you want to happen.

So, it is proposed to introduce a system for tracking all changes to middle or large code fragments. Each code fragment should be marked with the specific id. If the model generated a change in the code fragment, it should also request the result of difftool, analyze them, and only if everything is in order — send the result to the user.
