The frontend deps step occasionally crashes with "Segmentation fault (core
dumped)" (exit 139) during `npm ci` — a memory/native flake on the act_runner,
unrelated to the change under test (it failed the deploy-fix PR whose only change
is the Dockerfile). Retry once with a clean node_modules before failing.

The prod deploy failed restoring a transitive package
(Microsoft.CodeAnalysis.Workspaces.Common) with NU3008 "package integrity check
failed / has changed since it was signed" — a transient corrupted download on the
build host, not a code change. Wrap the backend `dotnet publish` so that on any
failure it clears all NuGet caches and retries once, re-downloading the package
fresh.
