Goals

Extend the existing JSON Arrow table support with schema-aware conversion, recovery logging, and GeoJSON-specific GeoArrow output, while cleaning up the GeoJSON public API.

Changes

• Replaces the simple JSON row-to-Arrow conversion with schema-aware nested JSON conversion.
• Adds json.schema / ndjson.schema and strict-by-default arrowConversion recovery policy support.
• Preserves streaming metadata batches and freezes Arrow schemas on the first non-empty data batch.
• Adds non-spammy one-time recovery logging through normalized loader logs.
• Promotes GeoJSON loader/writer exports by removing underscored experimental exports.
• Moves GeoArrow WKB output to GeoJSONLoader via geojson.shape: 'arrow-table'.
• Replaces gis.format with geojson.shape, including binary-feature-collection.
• Moves shared GeoJSON-to-GeoArrow conversion into @loaders.gl/gis; @loaders.gl/geoarrow delegates to it.
• Adds CRS preservation for GeoJSON-to-GeoArrow conversion.
• Extends JSONWriter to handle Arrow table inputs.
• Updates JSON/NDJSON/GeoJSON docs, release notes, and upgrade guide.
• Adds coverage for schema conversion, recovery policies, logger behavior, streaming schema freeze, GeoArrow metadata/CRS, official exports, and writer Arrow input.
