Can't run on headless machine

[ItsLucas]

I have a machine that don't support X11 (Apple Silicon Macs only support Wayland)
When I'm trying to run copilot-api, it spits out:

✔ Select a model to use with Claude Code
claude-sonnet-4

✔ Select a small model to use with Claude Code
gpt-4.1

I think these clipboard issues have something to do with clipboardy (https://www.npmjs.com/package/clipboardy). Or maybe with how I'm using clipboardy

I've been thinking to instead detect cli clipboard manager and use it if it's available.
So when copying it would look something like:

Is this X11? Is xclip installed? use xclip
Is this wayland? is wl-copy installed? use that
etc.
If nothing is found then just output the command.

I don't really know about other OSes though. Gonna do a bit of research first.

Maybe I shall hack this locally to put command to the console so I can somewhat make it useable first😂

I've added a catch block, so it outputs the command when clipboardy fails.

It doesn't fix the underlying issue but hopefully it's enough for now.
