test(eng-batching): bind unsourced native briefs through the report's target

Run 36606688266 asked ten separate native review questions (D1-D9 bound
to ledger records R1-R9) and failed reviewCount=0 < FLOOR=3: its briefs
named the plan by title instead of citing PLAN.md, its report declared
'Review target (fixed): PLAN.md' under '# Engineering review: <plan>', and
it kept an unfenced copy of the plan's own H1. The named-source route now
accepts those spellings and non-inline ledger briefs. The same replay
rejects a foreign, mixed, duplicate or missing target, another plan's
title or copied H1, a brief naming another plan or file, a mismatched
saved brief, and re-asks. The run-36597762183 capture still counts 3.
