PraisonAI Adapters - Implementations for core protocols.

This module provides concrete implementations of:

* Reader adapters (AutoReader, LlamaIndexReaderAdapter, MarkItDownReaderAdapter)
* Vector store adapters (ChromaAdapter, PineconeAdapter, etc.)
* Retriever implementations
* Reranker implementations
* CLI protocol adapters (C8.5: ServeHandlerAdapter, template store helper)
