Subject: [PATCH] fix(workflow): properly propagate parallel build errors on
 Vercel

`wait` without arguments returns only the last process's exit status,
so a failure in the first background build was silently swallowed.
Capture PIDs and wait on each explicitly to ensure any failure blocks
the Vercel deployment.
