gitui-org/gitui ? reverse-engineered prompt

Build me a fast terminal app for working with git, like a simple GUI inside the command line.

I want to be able to see my repo status, stage and unstage files, hunks, and even individual lines, write commits, amend them, stash changes, browse commit history, inspect diffs, manage branches, and push or fetch from remotes. It should feel really keyboard friendly, with clear on screen hints so I do not have to memorize a ton of shortcuts.

Make it responsive even in big repositories, and keep the interface clean and readable in a terminal. If you need to check current docs or behavior for git commands, look them up online. Also include support for submodules and the basic commit signing flow if that is practical.
