AIBIAS 2.0.0-preview

Added

• AIBIAS v2 preview: 239 bilingual questions (163 public, 76 private), four conditions (neutral, two opposite personas, "Are you sure?" challenge), hidden answer key.
• API track (OpenAI-compatible endpoints, resumable runner) and app track (numbered batches pasted into assistant apps, app-prompts / app-import, import refused if the pasted text differs from the generated one).
• Labelling by script and by a judge from another model family; dedicated pass on open questions separating settled claims from probabilistic forecasts.
• Metrics with 95 % bootstrap intervals; completeness rule (an incomplete model is never ranked); publish command (ranking + answers to public questions only).
• Preview results for three complete models in English (results/preview-2026-10/).
