feat(compare): support combined JSONL input and N-way multi-model comparison#382
Merged
Conversation
…parison Add combined JSONL mode that reads a single file with `target` field and produces an N-way score matrix. Supports --baseline/--candidate for pairwise filtering, --targets for matrix filtering, and exit code 1 on baseline regressions. Two-file pairwise mode remains unchanged. Closes #381
