Subject: [PATCH] ci: serialize release workflow runs via concurrency group

GitHub occasionally dispatches two workflow runs for the same push to
main, causing a duplicate release build that races semantic-release
and fails at the push step once the first run has already advanced
main. Queuing runs instead of racing them avoids the wasted build and
the spurious red X.
