Consider atuin for a history management tool

https://github.com/ellie/atuin

I currently use this [fzf integration](https://github.com/colindean/hejmo/blob/master/bash_profile/99_fzf.sh). It's great but the promise of atuin is rather seductive.

Start by reading bash_profile/99_fzf.sh and reviewing the linked atuin project. The issue does not identify an entry point, desired integration behavior, or acceptance criteria, so the first step is to define how atuin should replace or complement the existing fzf history workflow before implementation.
