Issue #2123

I tried installing OpenShell a couple of weeks ago but it failed as there was no install path for Arch Linux.

After some back-and-forth with Claude, it concluded that there are only installation paths for Debian and RPM. Claude then tried to persuade me into tricking the script that I was on Debian by installing some package, and that's when I wondered if there was another way? Surely, OpenShell already shipped tarballs that I could install! There just wasn't any logic for it in the installation script.

So, I want to add a bit of logic to install.sh to also identify pacman systems and install the Arch-compatible tarball.

Why this change?

To support all of the Arch users out there! We also deserve safe runtimes for our agents <3
