tmux
tmux, the session manager: panes, windows, popups and the dev layout.
tmux keeps work sessions alive and splits one terminal into panes. On the workstation it is how a repository becomes a workspace: Claude Code, lazygit and a shell side by side, one session per repo or branch.

devshell function builds the standard layout (see below).
