Updated the AppImage CI workflow to explicitly verify built-in plugin .so files are present in AppDir after install, checking checksum, fishlim, lua, perl, python, and sysinfo (and therefore excluding the Windows updater plugin from required Linux AppImage contents).

Updated the generated AppRun script to set ZOITECHAT_LIBDIR to the bundled plugin directory inside the AppImage (usr/lib/x86_64-linux-gnu/zoitechat/plugins with fallback to usr/lib/zoitechat/plugins) so plugin discovery resolves correctly at runtime from the AppImage payload.
