chriswalz/bit ? reverse-engineered prompt

Build me a modern Git command line tool called bit that feels easier to use than plain git.

I want it to work like git, but with smarter defaults, command and flag suggestions, autocomplete for file names and branch names, and helpful prompts when I type things like checkout or switch. It should support things like save, sync, pr, update, and the usual git commands too, so I can still fall back to normal git whenever I need to. Make it feel polished and friendly, with an interactive mode, some basic theme options, and clear output for things like branch status, stats, and debug info.

Please make it a single Go binary and keep it compatible with normal Git repos. If you need to check current docs for GitHub CLI or git behavior, look them up online. Also include the little quality of life stuff like branch fast forwarding, alias support, and tab completion so the whole thing feels modern and effortless to use.
