The watchdog fires on a "no progress" window, so the default mainly
matters for commands that go fully silent (no outputDelta). Bumping
from 2m → 3m leaves more headroom for legitimately slow silent
commands before treating them as a dropped function_call_output, at
a modest cost to recovery latency.
