v1.141.0

Fixed

• A claim on a metric the base does not have is judged. compare_results kept only the
  metrics both sides measured, so a metric that a change adds, its chart and its claim
  vanished from comparison.json and evidence.md without a warning. The comparison now
  has a top-level claims list with one entry per claim the candidate declares, judged on
  the candidate, with the baseline's outcome or null where the baseline does not measure
  that metric. evidence.md lists the claims above the charts. A metric that only one side
  declares is named in unpaired, in a "Not compared" list in evidence.md and in a
  warning from bencher compare and bencher ab. metrics and the exit status do not
  change: a failed claim is reported, not enforced. When the two sides share no metric the
  compare still fails (exit 1) and no claim is judged; the error now names the metrics on
  each side. schema_version stays 1, because the new keys are additive.
