The broadcast ticker logged seven fields at Info level every tick and
built a full state snapshot to do it, before checking whether any
WebSocket subscriber existed. An idle server paid a snapshot copy plus
roughly 8600 log lines a day for nothing. The log is now Debug and both
the log and the snapshot build sit behind the subscriber check.
The poll task worker pool was also fixed at ten workers no matter how
many instances an estate monitors. POLL_TASK_WORKERS now overrides the
count and the cap, bounded at 128, following the existing env knob
pattern. Behavior without the variable is unchanged.
Contract-Neutral: operational log demotion and an opt-in worker pool env knob, no monitoring or agent-lifecycle contract semantics change
