pub fn flush(source: &str)Expand description
Sends accumulated action telemetry to Sentry and clears the counters.
Should be called once on graceful shutdown, while the Sentry guard is
still alive. source is used as the Sentry event message (e.g.
"UI Action Telemetry" or "Server Action Telemetry"), allowing UI and
server events to be distinguished in Sentry.
The event is tagged as usage-telemetry so the logger’s before_send
filter lets it through even when crash reports are disabled.
