Feature Request: magit/fugitive like functionality

[heliostatic]

I'd love integrated git tooling.

It could be something like https://github.com/magit/magit or https://github.com/tpope/vim-fugitive, or a wrapper around gitui/lazygit like https://github.com/kdheepak/lazygit.nvim.

Today, I just have https://github.com/extrawurst/gitui/ in another tmux pane, which is fine, but having some amount of this functionality built-in would be great.
