Subject: [PATCH] fix(release): omit redundant setup-node cache selection

Use the established setup-node disable contract: no explicit cache backend and package-manager-cache false. The empty cache value was rejected by the workflow trust guard; retain the guard and add an omission check.

Contract-Neutral: The exact published-RC browser, credential isolation and cache prohibition contract is unchanged; this fixes its setup-node representation.
