iOS runner watchdog stalls for minutes on a large accessibility tree, and close/open does not recover it

What happened

agent-device 0.21.1, iOS simulator, a React Native app whose Home screen holds a long chat list. The first snapshot or press ... --settle on that screen makes the runner crawl the tree for two to three minutes; every command in that window returns:

The iOS runner is still finishing a previous command that exceeded its execution watchdog

agent-device close followed by open on the same session does not stop the crawl; the runner keeps going until its own restart. Seen on every run of a multi-run test (five runs, two days). A queued press after the stall sometimes did not land at all.

Proposal

Bound the crawl (depth or node count) with a partial result and a note, rather than exceeding the watchdog; and have close actually abort the in-flight command so a fresh open starts clean.

Riproduci nel simulatore iOS con una schermata React Native contenente un grande albero di accessibilità, iniziando con snapshot o press ... --settle. Traccia il crawl dell’albero di accessibilità e il watchdog di esecuzione, quindi esamina come close gestisce un comando in corso. Il lavoro è completo quando gli alberi grandi restituiscono un risultato parziale con limite e una nota, e close seguito da open interrompe il crawl precedente.
