• Upgrade to math.gl 5.0.0-beta.10 and reuse its Arrow worker transport and sparse row selection helpers.
• Return native Apache Arrow tables and record batches across loaders, scan sources, queries, and shared conversion APIs. Preserve per-batch metadata and row counts in worker transport.
• Build typed Arrow projections from CSV and NDJSON, push supported queries into DuckDB, and skip Parquet row groups outside the requested page.
• Consolidate parser and source descriptors under Loader names and remove redundant entry points and option aliases. See the upgrade guide for API changes.
• Align example dependencies with deck.gl 10.0.0-alpha.1 and share one build across release tests and npm publishing.
