The review model routinely narrates the pre-existing bug a PR fixes as a
critical/confirmed correctness finding; deriveVerdict then failed the very
change that fixes it (three consecutive A-grade reviews of shreai#188
verdicted fail this way). Findings now carry resolved_by_this_change
(prompted, schema'd, normalized); resolved findings are excluded from
fail/warn derivation, and a model-level warn whose findings are all
resolved normalizes to pass. Introduced-or-remaining defects still block.
