Fix all issues

Run PR review as a bounded state machine. The main agent owns orchestration, durable state, capacity, progress, and the final report. A fresh coordinator and blind reviewer pool own each outer round. Reuse a small fixed worker pool inside the round unless a gate requires independence.

The workflow must not choose between infinite scope growth and silently ignoring known issues. Attribute every verified finding, classify its responsibility, then either fix it in the current PR or record an explicit route.
