Hi, I have a difficulty running ssh exe.dev in Warp terminal with fish shell: Before registration: ``` $ ssh exe.dev Please complete registration by running: ssh exe.dev Connection to exe.dev closed.

After registration via bash workaround: see attached image

What works: 
- `bash -c "ssh exe.dev"` — in MacOS Warp terminal with fish shell
- `ssh exe.dev` — in MacOS Terminal app with fish shell
- `env TERM_PROGRAM=xterm-256color ssh exe.dev` — in MacOS Warp terminal with fish shell

Warp terminal incompatibility?

Looks like fish / Warp together are attempting to run commands immediately on connection for every ssh connection. But they're mistakenly assuming that the exe.dev repl is a linux machine.

We can probably detect and swallow this, or otherwise prevent it.

This is Warp falsely assuming that all ssh connections have a *nix box terminal on the other end.

Until they fix that, I've put in a workaround. It's in prod now--please feel free to re-open if it's not fixed for you. Thanks for your work diagnosing/debugging.
