VNX-GH-006: Release workflow restores a cache writable by untrusted runs
A workflow that publishes releases restores dependency caches that other workflows on the default branch can write.
Caches are shared across workflows in the same branch scope. A compromised or injectable workflow on the default branch can save a poisoned cache entry that a release workflow later restores and ships inside a published artifact.
