ReportWatchdogFaultIfNeededAsync built the StaHung fault with CommandMethod = snapshot.CurrentCommandCorrelationId, so the wire fault's command_method field carried an opaque correlation id (or empty) instead of a method name -- a consumer reading CommandMethod as a method name got a confusing value. Use a stable "Watchdog" label and fold the stuck command's correlation id (when present) into the diagnostic message instead. No test asserts CommandMethod for the StaHung fault; the existing assertions only check Category and that DiagnosticMessage contains "STA activity is stale", both unchanged.
