Confirmed live: /var/log/tinode.log-only redirection meant Loki never
received a single real tinode runtime log line (election, rehash,
connection, error output) since the container started -- Promtail
collects standard container stdout/stderr, not files written inside
the container. Every Pod's collected log was just this script's own
"NO_DB_INIT=true: skipping..." init line, nothing from tinode itself.
Now more consequential with native Cluster enabled: failover/rehash
state transitions were completely invisible to the normal Grafana/Loki
monitoring path, visible only via manual kubectl exec.
tee mirrors to both stdout (collected) and the file (still readable via
kubectl exec). PIPESTATUS[0] is required since a bare $? after a pipe
would report tee's exit status, not tinode's -- which also let this
drop the now-redundant "tail last 200 lines to stderr on crash" block,
since the full live stream already went to stdout throughout the run.
