shells/iris: Add port: Shell auto-completion tool for your terminal
IRIS is built on top of TTY, so it runs everywhere. It just needs a
terminal!
Run iris wherever you already work; your local machine, a remote
server, or anywhere you can ssh. Each suggestion menu renders directly
inline inside your real terminal session, not an app's imitation of
one, so it never breaks full-screen TUIs or terminal
formatting. Automatically index your aliases and shell history to
suggest commands that match your actual workflow in real time. Change
configurations and propagate them instantly without restarting your
shell. One single local native Go binary, not an app: no gui, no
electron, no mac-only wrapper, no account, no telemetry. (if you've
used fig: it's that, rebuilt to run purely on TTY)
