ci(review-answered): re-run a red gate when any internal review completes, not only the degradation

[rbuergi]

Why

On 2026-10-03 the control instance queued the internal reviewer's rounds behind its capacity bound for more than 75 minutes. Core #6014, #6017 and #6018 were reviewed after Automatic review answered had finished its 15-minute wait and published red. The review's arrival then re-ran nothing that branch protection reads, so core merged nothing until someone pushed.

review-answered-on-degradation.yml already does the right thing: it re-runs the newest pull_request run of the gate for the head. Until now it did that only for the "Reviewer unavailable" degradation.

What

• The listener now fires on any completed internal-review check run from the internal reviewer's App (systemorph-com, 4918443), whatever its conclusion. It still lets gate runs that are in flight finish, and leaves a gate that already reads success alone. The re-run judges the head itself, so this changes no verdict.
• Job and step names now say what the listener does. They are not required contexts, and nothing references them.
• Doc/Architecture/ReviewFindingsAnswered records the change and the incident.

The companion admission fix (reviews unlimited while the model pool has headroom) is Systemorph/MeshWeaver.Plugins#2746.
