- Remove debian/compat file (conflicts with Build-Depends)
- Fix debian/install to use correct readme.md filename
- Update verify-deb.sh to mark debian/compat as optional
- Add -Zgzip flag to dpkg-buildpackage for compatibility
(uses gzip instead of zstd for better compatibility)
- Update verify-deb.sh to check optional vs required files
Package now builds and installs successfully on systems
without zstd support.
