Latest AppImage incompatible with Debian Trixie

[chlarsen]

Bug Description

First of all, a huge "Thank you!" for all your great work!
Alas, with the latest upgrade, Extera seems to have moved out of the realms of Debian Trixie and its offspring, as AppImage version 26.4.2 requires GLIBC version 2.43, but Debian Trixie only offers version 2.41. Any thoughts?

Steps to Reproduce

Install the latest AppImage (version 26.4.2) on Debian Trixie, MXLinux and derivatives.

Expected Behavior

Extera starts up and everything looks fine.

App Version

26.4.2

Additional Platform Information

Debian Trixie on Intel

Additional Context

Extera silently crashes, but the command line says:

$ /opt/Extera/Extera_Next.AppImage 
./extera_next: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.43' not found (required by /tmp/.mount_ExteraDfkjoi/lib/liblivekit_client_plugin.so)

when flatpak version becomes available, we will most likely get rid of appimage build.
afair, appimages should be compiled on the oldest system possible to prevent such issues, but it seems it wasnt our case.
i personally dont think there is much point in fixing appimage now. this could be done quite easily, though, by building on debian
