[FEATURE] Separate diff engine fol claude code change proposal

[alex-popov-tech]

Feature Description

Hello! I was wondering would it be possible to delegate visual side of claude code diffs proposal to more focused plugins, like https://github.com/esmuellert/codediff.nvim or diffview.nvim ?

Use Case

They do better job of showing differences than a built-in implementation, and visually much more pleasant to work with
