fix: restore step died with exit 141 (SIGPIPE) on every cache hit — act runs step scripts with 'bash -e -o pipefail', so the 'FIRST_ENTRY=$(tar -tf ... | head -1)' detection line killed the step: head -1 closes the pipe after the first line, tar gets SIGPIPE (141), and pipefail propagates it as the script exit status (observed: 'Cache hit' then 'Process completed with exit code 141', step duration 0s, on deploy-leptos after this detection line was added on 2026-08-14)

The previous restores predate the detection line, which is why this only started failing on 2026-08-17. Suppress the pipeline status with '|| true' — FIRST_ENTRY still captures the first archive entry, and a genuinely unreadable archive degrades to the legacy fallback / cache-hit=false path as before.
