fix: lazy-load ArrowSerializer to avoid ImportError without pyarrow#44
Conversation
ArrowSerializer was unconditionally imported at module load time, causing ImportError for users who install cachekit without the [data] extra (pyarrow). Changes: - Remove top-level ArrowSerializer import - Add lazy loading via _get_arrow_serializer() helper - Use __getattr__ for lazy attribute access - Update SERIALIZER_REGISTRY to use None placeholder - Fix benchmark_serializers and get_serializer_info to handle lazy loading gracefully Users can now: - pip install cachekit and use default serializers - pip install cachekit[data] to enable ArrowSerializer Fixes #41
