Module traits 

Core traits for RAGFS components.

This module defines the trait interfaces that all RAGFS components implement:

• ContentExtractor: Extract content from files
• Chunker: Split content into chunks
• Embedder: Generate vector embeddings
• VectorStore: Store and search vectors
• Indexer: Coordinate the indexing pipeline

These traits enable a pluggable architecture where different implementations can be swapped without changing the rest of the system.
