Summary

• Produce AppImage compatible with Ubuntu 22.04 (glibc 2.35) and Ubuntu 24.04.
• Prevent bundling core system libs that force newer GLIBC.
• Add CI guard to fail builds if AppImage embeds libstdc++ requiring GLIBC ≥ 2.36.
• Document Linux runtime packages (EN/TR/ZH).

Context/Motivation

• Users on Pop!OS 22.04 were unable to run AppImage due to embedded usr/lib/libstdc++.so.6 requiring GLIBC_2.36/2.38.
• AppImage cannot safely ship glibc; must rely on host glibc and avoid shipping newer libstdc++.
• Ensure predictable releases across Ubuntu 22.04/24.04.

Changes

• linux/packaging/appimage/make_config.yaml
• Add exclude list to avoid bundling: libc.so.6, libpthread.so.0, libdl.so.2, libm.so.6, libresolv.so.2, librt.so.1, libstdc++.so.6, libgcc_s.so.1.
• Keep sqlite libs included.
• linux/packaging/deb/make_config.yaml
  Remove -dev runtime dependency (keep libsqlite3-0 only).
• .github/workflows/build.yml
• On ubuntu-22.04 build: install libstdc++-12-dev, patchelf.
• After packaging, extract AppImage and check for GLIBC_2.36/2.38 symbols in usr/lib/libstdc++.so.6; fail if found.

Docs

• README.md: Add “Linux Requirements (Ubuntu 22.04 and 24.04)”.
• README_TR.md: Add “Linux Gereksinimleri (Ubuntu 22.04 ve 24.04)”.
• README_ZH.md: Add “Linux 运行环境需求（Ubuntu 22.04 与 24.04）”.

Testing

• Local: Built AppImage on Ubuntu 22.04 environment; verified no embedded libstdc++ with GLIBC_2.36/2.38 symbols.
• Runtime: Manually tested AppImage on Pop!OS 22.04 and Linux Mint — launches successfully.
• CI: New symbol gate will fail builds if incompatible libstdc++ is bundled.

Backward Compatibility

• AppImage now targets host glibc and should run on Ubuntu 22.04 (glibc 2.35) and 24.04.
• DEB dependency cleanup does not remove required runtime libraries.

Operational Notes

• If users hit X11/GLX issues on certain drivers, suggest trying Wayland or forcing Mesa/software path as documented.
• Consider adding an optional CI step to assert presence of AppRun in extracted AppImage if needed.

Checklist

• AppImage excludes core system libs
• CI symbol gate for GLIBC 2.36/2.38
• Docs updated in EN/TR/ZH
• Local validation on 22.04-based systems
• Local validation on 24.04-based system
