The meta-eval runner now judges the stored A/B order with the task's default PairScore prompt (temperature 0.5) and writes annotations.parquet alongside the sample. Agreement is reported on all battles and on the subset that drops human ties, with bootstrap standard errors. Judge inputs are serialized to strings before they are stored, so later cache backends do not have to bind a LangChain prompt object.

Two runs of the same task and judge under different prompt presets or swap modes wrote to the same result directory, so the second silently overwrote the first. Both now appear in the folder name, and the report records the preset the verdicts were parsed under. The tie boundary also moves back to the original one: a preference exactly eps above 0.5 is a tie, not a model_a win.

Description
Note
WIP: packaged meta-eval split from closed PR #76. Caching is not in this stack; it stays with the unified
do_inferencecache PRs.Judges the sampled battles in stored A/B order and reports accuracy and Cohen's kappa with bootstrap SE. Agreement is written for all battles and for the no-human-tie subset.
PairScore temperature is 0.5 here (paper / Figure 4); generate+judge stays 0.3.
This is stacked on #101.
