• Backend Logic:
  • Introduces InferenceWithFeedbackStatsResponse type in InferenceWithFeedbackStatsResponse.ts.
  • Implements build_count_metric_feedbacks_query() and build_count_demonstration_feedbacks_query() in inference_stats.rs for querying feedback metrics.
  • Refactors ClickHouseConnectionInfo to implement InferenceStatsQueries trait for feedback metrics.
• Frontend Updates:
  • Updates count.route.ts to use getInferenceStats() and getFeedbackStats() from tensorzero.server.
  • Removes old ClickHouse query functions from curation.server.ts.
• Testing:
  • Adds E2E tests in inference_stats.rs for new API endpoints.
  • Updates unit tests in tensorzero.test.ts to cover new client methods.
