Subject: [PATCH 1/3] fix: upgrade openshell when installed version is below
 minimum

The install script previously exited immediately if openshell was
already installed, regardless of version. Users on 0.0.6 would stay
on 0.0.6 and hit cgroup v2 failures fixed in 0.0.7 (OpenShell#329).

Now checks the installed version against a minimum (0.0.7) and
upgrades automatically if too old.

Closes #136
