Short tunnel re-negotiations recover internally; a kubelet restart only
prolongs the outage while the kill switch already blocks all egress.
Liveness budget 60s, readiness stays at 30s.
The image copies and patches the chromedriver binary to the hardcoded
path /app/chromedriver at startup (no env override exists) and writes
chromedriver caches under /app, so readOnlyRootFilesystem cannot hold;
deviation documented in values.yaml. Reverts the HOME=/tmp workaround,
which only covered the cache path, not the binary patching.
The image declares its non-root user by name only, which the kubelet's
runAsNonRoot check cannot verify (CreateContainerConfigError); pinning
the uid/gid numerically satisfies the check.
