Interactive TUI scratchpad for building shell pipelines

Rura is a terminal UI for building shell pipelines. Edit a pipe like grep | sort | uniq, see output update live, inspect any stage, and diff between runs — replacing the usual edit, up-arrow, rerun loop.
$ brew install rura$ yay -S rura-bin$ sudo rpm -ivh rura_<version>_<arch>.rpm$ cargo install rurato comment.
