AppImage v0.2.0 fails with Squashfs (null) compression error on modern kernels #15

Description

The provided AppImage for version 0.2.0 is not working on modern Linux distributions.

Errors Observed:

Standard execution: Squashfs image uses (null) compression, this version supports only xz, zlib.

Extraction attempt (--appimage-extract): This doesn't look like a squashfs image. Failed to open squashfs image.

Environment:

OS: Kali Linux (Rolling)
Kernel: 6.18.12

Note: The .deb version works perfectly, which suggests the issue is strictly with the AppImage packaging/compression.

Suggested Solution:

The AppImage seems to be using Zstandard (zstd) compression which is causing compatibility issues with libappimage and AppImageLauncher.

Please rebuild the AppImage using XZ compression by adding the -comp xz flag to appimagetool in your CI/CD pipeline. This will ensure it runs on both older and newer distributions.
