#4159 fad6d9a Thanks @haacked! - add $feature_flag_has_experiment to $feature_flag_called events
$feature_flag_called events now carry a $feature_flag_has_experiment boolean sourced from the server's has_experiment flag metadata (the /flags?v=2 response for remote evaluation, the /api/feature_flag/local_evaluation definitions for posthog-node local evaluation). The property is only sent when the server explicitly reports has_experiment; it is omitted entirely when the value is unknown (older servers, missing metadata, bootstrapped or locally injected flags).
