## Title

    Proposed fix: [qdrant-client local mode] RuntimeError "Storage folder ... is already accessed by another instance of Qdrant client. If you require concurrent access, use Qdrant server instead."

## Body

    Recommended action: Reuse a single client instance (cache it, e.g. st.cache_resource), close() it before reopening, or run Qdrant server (docker) for multi-process access.
    
    Option: Share one client or switch to server mode [evidence: official_recommended_action]
    Applies when: Web apps, notebooks, multi-worker servers
    Steps:
    1. Create the QdrantClient once and pass it to vector stores
    2. or run qdrant/qdrant in Docker and use url=...
    Expected: No lock conflicts
