* fix(desktop): preserve Linux sandboxing wherever the host allows it Chromium checks its Linux sandbox before main.js, while package installation probes run as root and miss AppArmor restrictions on desktop users. Choose the launch flags before exec and always install the SUID alternative for native packages. Test published artifacts as an ordinary user with namespaces both denied and allowed; never repair permissions in the smoke harness. * fix(desktop): retain the Linux release build baseline * fix(ci): allow canceled desktop smoke uploads to stop * test(desktop): verify the installed RPM sandbox under AppArmor * fix(ci): resolve packaged desktop dependencies before installation * chore(desktop): keep QA evidence out of the repository
