web search config is required for RAG compression

Error message

web search config is required for RAG compression

What it means

Configuration guard at the top of CompressWithRAG: the method needs settings from *types.WebSearchConfig (model selection, parameters) to build the temporary knowledge base for RAG compression, and a nil cfg was passed. It fires when the search/compression pipeline is invoked without a web search configuration.

Solutions

1. Pass the web search config used for the original search into CompressWithRAG
2. Verify the caller's config was loaded before compression
3. Fail the compression request and ask the client to configure search
