<!-- PR titles must follow Conventional Commits: <type>(<optional-scope>): <description> --> ### Purpose <!-- Linking this pull request to the issue --> Linked issue: close #214 Support predicate pushdown in `DataEvolutionSplitRead`, aligned with the Java implementation. - Push predicates to file indexes and format readers for single-file row-id groups. - Use file indexes only to skip whole merged groups, avoiding row misalignment between files. - Exclude system fields and predicates outside the read schema from pushdown. - Ignore stale indexes for fields overwritten by newer files. - Compose bitmap index selections with row ranges and deletion vectors. - Skip blob and vector-store files when evaluating merged-group indexes. <!-- What is the purpose of the change --> ### Tests Added and updated tests covering: - Predicate selection by read schema and system-field exclusion. - Single-file bitmap and format-level predicate pushdown. - Merged-group pruning and column alignment. - Stale indexes on overwritten fields. - Missing physical predicate columns. - Bitmap selections intersecting row ranges with empty, partial, and non-empty results. - Physical row-id preservation after bitmap selection. - Parquet page-level and ORC row-group predicate pushdown without file indexes. <!-- List UT and IT cases to verify this change --> ### API and Format <!-- Does this change affect API in include dir or storage format or protocol --> ### Documentation Generated-by: Codex (GPT-5) <!-- Does this change introduce a new feature --> ### Generative AI tooling <!-- If generative AI tooling has been used in the process of authoring this patch, please include the phrase: 'Generated-by: ' followed by the name of the tool and its version.
