Rolling deploy — only the monitor container was recreated, Minecraft was never
restarted, so no world downtime.
Records what was verified against real data rather than assumptions: the TPS
parse and RCON allowlist, the session parser against actual rotated-log join
lines, the level-regex fix (WARN/ERROR now distinguished where every line
previously read INFO), collector isolation with mc-status killed, and the
concurrent-refresh latency win.
