### Purpose Linked issue: close #258 Add core integration coverage for Spark-generated mixed-format data-evolution tables. This complements the existing mixed-format schema-evolution tests by enabling `row-tracking.enabled` and `data-evolution.enabled` on the fixtures. MERGE and RowRange mixed-format data-evolution cases are intentionally left for follow-up because local validation exposed independent Spark/Paimon or reader behavior issues. This PR keeps the coverage focused on stable core read behavior. ### Brief change log - Add `data_evolution_mixed_format_add_column` with Parquet old-schema files and ORC/Avro new-schema files. - Add `data_evolution_mixed_format_type_promotion` with Parquet INT files and ORC/Avro BIGINT files. - Add core read tests for scanned file formats, multiple schema ids, add-column null-fill, INT-to-BIGINT promotion, and `_ROW_ID` projection. ### Tests - `python3 -m py_compile dev/spark/provision.py`: passed - `cargo fmt --all -- --check`: passed - `make docker-up`: passed - `cargo test -p paimon-integration-tests --test read_tables data_evolution_mixed_format -- --nocapture`: passed (`3 passed`) ### API and Format No API or storage format changes. This is fixture and integration-test coverage only. ### Documentation Not required; no user-facing behavior or API changes. -- This is an automated message from the Apache Git Service.
