AppImage files use SquashFS format (ELF + embedded squashfs), so bsdtar
fails with "Unrecognized archive format". This was causing Linux beta
builds to fail at the verification step.
Changes:
- Replace bsdtar with unsquashfs for AppImage inspection, with fallback
to --appimage-extract and finally size validation
- Use boundary-safe regex for app.asar detection (avoids false positive
from app.asar.unpacked)
- Tool execution failures now correctly trigger verification failure
- Missing package targets are hard failures instead of warnings
- Install squashfs-tools instead of libarchive-tools in CI workflows
