docs: reconcile BACKLOG→RETRO for static_check stage + critique producer (e46777e)

Per the hygiene rule: the §B-§5 static_check stage seam + emitter and the §B-§6/A3
critique-outcome producer are built and unit-verified, so move them out of the live
"missing" list. Both narrowed to their remaining live-QA-gated *activations* (a sandboxed
production CommandRunner for §B-§5; model-emitted CritiqueFindingsRecordedEvents for §6),
with a dated RETRO entry + commit map. Updated QA-reviewer-static-first (the producing
stage now exists — check 4 reframed from "blocked on unbuilt seam" to an activation step)
and its README index line.
