The old probe did a subscribe-read-unsubscribe cycle every 5 seconds to check connection health. This created unnecessary churn and didn't detect the failure mode where long-lived subscriptions silently stop receiving COM callbacks (e.g. stalled STA message pump). The new approach keeps a persistent subscription on the health check tag and forces reconnect if no value update arrives within a configurable threshold (ProbeStaleThresholdMs, default 5s). Also adds STA message pump debug logging (5-min heartbeat with message counters) and fixes log file path resolution for Windows services.
