Address review findings:
- Add trap for temp dir cleanup on error
- Use -Zxz for max distro compatibility (older dpkg lacks zstd)
- Use --root-owner-group for correct file ownership

jpackage runs `dpkg-shlibdeps` against the bundled JDK runtime's native
libs (libfontmanager.so etc. link libicu) and pins Depends to the build
host's libicu version. CI builds on ubuntu-24.04, so the .deb requires
libicu74 — uninstallable on Ubuntu 22.04 (libicu70), Debian 12 (libicu72),
Debian 11 (libicu67), and Debian 13 (libicu76). Neither jpackage nor the
Compose Multiplatform DSL exposes a way to override the auto-generated
Depends.
Add scripts/relax-deb-libicu.sh which extracts the .deb with `dpkg-deb -R`,
rewrites `libicuNN` (or any alternation thereof) to
`libicu66 | libicu67 | libicu70 | libicu72 | libicu74 | libicu76 | libicu77`,
and repacks. The script is idempotent and a no-op for .debs without a
libicu Depends.
Wire it into both release legs (desktopApp + amy CLI) in
create-release.yml, and into the desktop test/build leg in build.yml so
testers downloading the CI artifact hit the same fix.
