Artix and other non-systemd arch-based operating system support

[larpedd]

Problem

currently, the flag from ./install.sh: --force-unknown-distro doesnt account for arch-based operating systems or non-systemd operating systems. and it also doesnt take account for package managers. (currently the flag just forces you to use apt even if the operating is not debian based.)

Proposed solution

add a solution that would fix this issue, or rewrite the ./install.sh script to take account all of the mentioned issues above.

Alternatives considered

@larpedd I opened draft PR #77 with Artix/pacman detection, package-manager-aware fallback, and a non-systemd path that skips automatic service setup and prints per-user supervisor guidance.

We do not have a real Artix/non-systemd desktop to validate this end to end. Could you test ./install.sh from the PR on your system, then share which init you use (OpenRC, runit, s6, or dinit), the installer output, and computer-use-linux doctor output? I’m happy to help work through any failures and adjust the PR for your setup.
