fix: update npm package.json description and keywords to match actual tool

Description was generic ('Declarative data transformation pipeline'),
now correctly describes DataMorph as a batch data format converter.
Keywords updated to include format-specific terms (csv, parquet, avro,
schema-validation) for better npm discoverability.
