     List knowledge bases, files, and notes attached to the current model.
-    Use this first to discover what knowledge is available before querying or reading files.

     Without knowledge_id: returns KB summaries (name, description, file_count)
     plus standalone files and notes — no file listing inside KBs.
     With knowledge_id: includes paginated file listing for that specific KB.
