// tab_events — inyector de TableEvents sinteticos para auto-test del event sink.
// Issue 0108 fase 2.
//
// Patron: se construye un vector<TableEvent> LOCAL y se llama qa::consume_events
// directamente — sin worker thread. Los counters de qa::counters() se incrementan
// como si el usuario hubiera clickado. Ademas se renderiza la tabla real para que
// eventos reales y sinteticos cuenten igual.
//
// Inspirado en altsnap_jitter_test: fakear eventos de bajo nivel directamente
// sobre el estado interno del subsistema, sin depender de la UI.
