The config key is declared in DEFAULT_CONFIG and shown in the auxiliary
config UI, but the judge path never read it — a user raising the timeout
for a slow-but-healthy endpoint got the same 30s cap, and the loop
auto-paused on transport failures advising a provider/key check. Mirror
the _goal_judge_max_tokens reader and resolve the timeout at call time;
explicit timeout= arguments still win.
