📄 Description

Added native function calling support for knowledge bases with citations

Changes

Added query_knowledge built-in tool that searches model-configured knowledge bases when native FC is enabled
Fixed citations and UI display for native FC tools (web_search, query_knowledge) - results now show in WebSearchResults UI and model cites sources automatically
Updated tool descriptions to prioritize knowledge bases over web search
Filtered knowledge base metadata to only include essential fields (name, page, total_pages, creationdate)

Behavior

When native FC is enabled, knowledge bases are not auto-injected -> model decides when to query them
Tool results are converted to sources and emitted as events for UI display
Sources are injected into RAG template so model can cite them
Model checks local knowledge bases first before searching the web
Manual file/KB attachments continue to work as before
