v5.0.0-alpha.4

• feat(parquet): expose encoded pages for deferred decoding and future query execution
• feat(zarr): add SpatialData container source support
• refactor(loader-utils): compose source capability interfaces for shared scan metadata

• feat(scan): incubate Hudi, Iceberg, and Delta Lake scan adapters behind the scan module
• feat(avro): publish Avro as a standalone format module with lightweight package-root exports
• feat(parquet): keep compression implementations in @loaders.gl/compression and reduce the Parquet package footprint
