Diagnostic for #178, meant to be deleted once it has answered.
actions/cache refuses to run on these runners, printing its GHES warning,
on both v3 and v4. Two explanations survive and they need different fixes:
cache is off in act_runner's config, so there is no ACTIONS_CACHE_URL and
nothing for the runner's bundle patcher to aim at; or a cache is served
and the patcher does not recognise these bundles, leaving the gate shut,
which would be a runner bug to report upstream.
Whether the runner exports a cache URL separates the two. The job needs no
PHP, so it stays off the slow setup-php path and answers in seconds.
URLs are printed as values since they are plain endpoints. Tokens are
reported as set or unset only, and the second step lists variable names
without values, so no credential reaches the log.
