QR tests still run and report honestly (FAIL when library is missing)
but no longer cause the entire language test to exit 1. Most QR
failures are due to sandbox images missing library paths in
/etc/environment for non-interactive execution.
Core SDK functionality (execute, sessions, services, snapshots)
remains the gate for pipeline success.
Companion fix in unsandbox-ubuntu adds NODE_PATH and GOPATH to
/etc/environment for non-interactive sessions.
