setup-php resolves its tools through the GitHub API, unauthenticated at 60
requests an hour per source address. A CI fan-out across the fleet exhausts
that bucket, and the step then retries for several minutes before reporting
only "Could not setup PHP 8.3". It reads as a hang rather than a throttle,
and it took out both a main CI run and a release build.
Each cluster has its own egress address and so its own bucket, which is why
the same job passed on one runner and failed on another in the same minute.
The token comes from 1Password through the Connect instance in whichever
cluster picked up the job, matching the pattern in thatguygriff/infra. That
repository's composite action is not reachable from here, so it is mirrored
locally. It stays a step output rather than being exported to the job
environment, to keep it away from the package scripts composer install runs.
