Add EvalServer integration to v1beta with HTTP endpoints for test execution. Generate professional markdown reports with confidence scoring, collapsible sections, and trace links. Fix streaming bug in LLM judge by reading both Delta and Content fields. Add comprehensive documentation (docs/eval.md, docs/trace.md) with examples, best practices, and troubleshooting guides.
