Sonnet 4.6 with extended thinking on the triage prompt (~40k chars + AGENTS.md
+ skills) can take >3 minutes between thinking deltas. The 180s inactivity
timeout was killing those subprocesses before they could finish PROMPT.md +
fn_review_spec, leaving triage looping into the fallback model. Bump to 5
minutes.
Test mock timings updated to match.
