feat: gate linux installer on GLIBC version and disable auto-update f…

[charlypa]

…or old systems

The new AppImage is built on ubuntu-22.04 (GLIBC 2.35) and cannot run on older systems like Ubuntu 20.04 (GLIBC 2.31). When the installer detects an incompatible GLIBC, it sets "autoUpdate": false in phcode.json to prevent the old version from repeatedly attempting an upgrade that will never succeed.

Tested on ubuntu20 (2.31, refused), ubuntu26 (2.43, passed), fedora-44 (2.43, passed).
