[creative-idea] Add a self-merge governor that batch-verifies the ~30 green, merge-ready Simard PRs against the pr-merge checklist and lands the clean ones itself, instead of re-escalating 'verify-and-merge #XXXX' to the operator every cycle with prs_merged=0. #4166
originating-idea: pro_e5f160ccb6b1
Every recent overseer cycle reports 29–39 problems dominated by dozens of DeliveryReady PRs (#4080–#4162) that stay unmerged despite 30+ operator escalations and zero merges — the delivery bottleneck, not authoring, is now the binding constraint.
Routed for human review by the Creative Ideas thread (#2419).
