Add Starship

[Kasui92]

This PR adds Starship to Omakub, using Omarchy’s configuration and style as a reference for consistency.

I was actually thinking about that, but the way /defaults/bash are handled here is different from Omarchy. The risk is that anyone not using Starship could suddenly end up without a prompt. We’d probably need some kind of safeguard to avoid making the change too disruptive.

With #562 we would manage them in a similar way and then maybe do the migration more "gentle".

You're mistaken. You're misinterpreting what's happening here. We substitute the system prompt. It remains, it's not going anywhere. If something goes wrong, the system prompt will appear.
This is a continuation of my argument about PS1. I insisted there that if something goes wrong, let the system prompt return.

Anyone who doesn’t want to use Starship and prefers to stick with the old PS1 setup, with NerdFont and icons, would lose it immediately. That’s exactly what happened in Omarchy at first, because the PS1 wasn’t removed right away after Starship landed. I think the same approach makes sense here: phase it out slowly and give people who don’t want Starship a way to keep their existing prompt.

This is not the way of Omak. 😄

Yes, of course, it’s definitely less Omakase. But between removing the PS1 entirely and keeping it no matter what (which I don’t really see the point of either), I think there’s room for a middle ground if you want to switch everything in one go.

Maybe we could consider a migration step that adds the current PS1 back into .bashrc for anyone who doesn’t want to install Starship.

Otherwise, fine by me... we can just clean up the PS1 and move on. 👍🏻
