Purpose
Linked issue: #342
Add infrastructure for columnar-extend MAP storage layout, enabling
MAP<STRING, T>columns to be stored as physicalSTRUCT<__field_mapping, __col_0..K-1, __overflow>for better columnar performance.Key components:
ExtendMapUtils/ExtendMapDefine: Column detection, schema conversion, metadata serialization/deserializationCoreOptions: Per-column config (map-storage-layout,map-extend.max-columns)SchemaValidation: Validate extend layout configurationMapStorageLayoutenumTests
ExtendMapUtilsTest: Roundtrip serialization, schema conversion, column detection, error casesCoreOptionsTest: Layout and max-columns config parsingSchemaValidationTest: Extend layout validationAPI and Format
