## Which issue does this PR close? - Closes #2364. ## What changes are included in this PR? `IcebergTableScan` now owns a DataFusion `ExecutionPlanMetricsSet`, returns it from `ExecutionPlan::metrics()`, and resets it from `ExecutionPlan::reset_state()`. The scan output stream is wrapped in a small `poll_fn` adapter that records `BaselineMetrics` while the Iceberg stream is polled. This exposes the standard DataFusion operator metrics such as `elapsed_compute`, `output_rows`, `output_batches`, `output_bytes`, and completion timestamps in `EXPLAIN ANALYZE`. Focused tests cover the metrics wrapper directly and the catalog-backed provider execution path, including reset-state behavior. ## Are these changes tested? - `cargo test -p iceberg-datafusion stream_with_baseline_metrics_records_rows_and_compute --locked` - `cargo test -p iceberg-datafusion test_catalog_backed_provider_scan_reports_metrics --locked` - `cargo check -p iceberg-datafusion --locked` - `cargo test -p iceberg-datafusion --locked` - `cargo clippy -p iceberg-datafusion --all-targets --locked` -- This is an automated message from the Apache Git Service.
