_check_pm_decision_required now requires the latest journal:decision
within pm_decision_window_seconds (default 300). Older decisions no
longer satisfy the gate. Adds JournalService.latest_decision_at.
Future-tighten (out of scope): per-verb-group consumption tracking
would need persistent state — Choreographer is per-request today.
Smoke run 3 showed Main PM hitting 7 incomplete_input rejections on
the decision-note required-fields gate before finally succeeding.
The per-verb breaker tracks repeated rejections of the same verb in
a 60s window and returns circuit_open after the 3rd strike — but its
classification set only included tracing_gap. incomplete_input was
added in Wave 1 (pre-gateway parity for decision/reflect structured
fields) and should have been added to the breaker at the same time.
